Web Site Performance Management Tool

New network tools available (2005-01-31)

Network tools like web site performance management tool, traceroute and dig (for DNS), are now available for members as well as non-members. You can use these tools to investigate the behavior of your servers in more detail.
You can find these tools on the 'Tools' page.

More statistics: connect time and download time (2005-01-31)

For all web site performance management tools, WatchMouse measures the time it takes to connect to your host. For some web site performance management tools, we measure the time it takes to download the file or page too. In the Reports section, you can now find two graphs that reflect these figures:

• Average connect time
• Average download time

More reports will be added in the near future.

Site and services available in Greek (2005-01-31)

We're happy to make a Greek version available of our site and services (Alexandra, Peter, Mark, and Niels: thanks!), ready to be used by the Greek speaking population (Greek is the official language of Greece, where it is spoken by approximately 10 million people. It is also one of the official languages of Cyprus, where there are an additional 600,000 speakers. Beyond that, some 3 million people elsewhere in the world claim Greek as their first language, including numerous speakers in Turkey, Albania, Canada and the United States.[transparent.com]).

Dutch e-commerce sites poorly prepared for Christmas rush (2004-12-14)

Only 20% achieve maximum availability

UTRECHT, 20041205 -- Many Dutch e-commerce sites have made only minimal preparations for the increased number of visitors in December. The congestion caused by Sinterklaas [traditional Dutch celebration on 5 December] meant that, on average, only one in six sites was continuously available. This was the conclusion of WatchMouse, a Dutch monitoring site, following a survey of 25 e-commerce sites. Even worse figures are expected during the weeks before Christmas. Excessive interest from customers can overload the server or have dramatic effect on response times.

During the past month, WatchMouse – at its own initiative – closely monitored 25 sites where consumers can shop web site performance management tool, such as Bol.com, Wehkamp, Free Record Shop, De Bijenkorf, ECI, Bart Smit, Dixons and Bruna. The survey shows that the 'up time' – the time during which the server is web site performance management tool – varied from 98% to 99.6%. "This may seem high, but a score of 98% means that a site is not available for half an hour per day. This makes 14 hours a month, or a week a year", says Mark Pors, one of the founders of WatchMouse.

The consequences of this are reflected not only in loss of income. Pors: "A website that is not available can cause stacks of work for a helpdesk and, at the end of the day, damage the brand’s image. The problem is that many website owners are unaware that sites are responding poorly, or not at all. If they were aware of this, taking action to intervene is simplicity itself: for example, by adding extra server capacity."

WatchMouse has concluded from its survey that only 20% of the sites have achieved optimum accessibility. Given the increasing trend in web site performance management tool purchases, gigantic sums are involved. In the first six months of 2004, web site performance management tool expenditure rose to € 775 million; a 35% increase. Each web site performance management tool shopper spent € 227 from January through June of this year (Blauw Research, September 2004).

December is also a top month for purchasing on the internet. Pors: "We saw response times and the number of error reports increase dramatically in the days leading up to Sinterklaas. This does not bode well for the even busier period before Christmas."

Companies can easily monitor their internet sites themselves, thanks to WatchMouse’s monitoring service.

WatchMouse has been monitoring internet sites and e-commerce applications for companies across the globe since 2001. WatchMouse has thousands of users in more than 70 countries.

WatchMouse opens new monitoring stations in China and London (2005-01-12)

Largest monitoring network world-wide.

UTRECHT, 20041210 -- WatchMouse, active in monitoring websites world-wide, has opened two new monitoring stations: in Hong Kong and London. At the same time, the company’s station in Sydney, Australia, has been completely renewed. With this expansion, WatchMouse is responding to the explosive growth in interest in real-time site monitoring from e-commerce companies. With nine stations, the Utrecht-based company is now the largest monitoring network world-wide.

Thanks to rapidly increasing web site performance management tool expenditure via the Internet, services such as WatchMouse are undergoing significant development. A monitoring station provides insight into the availability of e-commerce sites, the speed of these sites and response times. Research performed among Dutch websites by WatchMouse has demonstrated that many sites are still missing out in this area. Mark Pors, one of the founders of WatchMouse: “As spending web site performance management tool is growing by tens of percentage points each year, it is in the interest of sites to obtain insight into how they are functioning. A server that is poorly accessible for half an hour or more a day loses lots of money. Companies are increasingly recognising that they are losing out, both in terms of turnover and image. Not only in the Netherlands, but also elsewhere. For this reason, we are setting up stations in more countries.”

Local testing

By creating a larger spread among the control stations, sites can be monitored from more points throughout the world. WatchMouse is responding to increasing demand from clients for a world-wide picture of site availability. WatchMouse’s clients can also stipulate a preferred station for 'local' testing. For this reason, China and Great Britain have been added as two strategically important markets for e-commerce. The Utrecht company’s other stations operate from Florida, Texas, Sydney, Nuremberg, Orleans, Amsterdam and Singapore.

European e-commerce sites poorly prepared for Christmas rush (2004-12-24)

Comparison with US "role models" Amazon and Barnes & Noble

THE NETHERLANDS, 20041223 -- Many European e-commerce sites have made only minimal preparations for the increased number of visitors in December. The congestion caused by Christmas meant that, on average, only one in six web sites was continuously available. This was the conclusion of WatchMouse, a Dutch monitoring service provider, following a survey of over 50 European e-commerce sites. Excessive interest from customers can overload the server or have dramatic effect on response times.

During the past month, WatchMouse – at its own initiative – closely monitored over 50 web sites where consumers can shop web site performance management tool. The survey shows that the availability varied from 98% to 99.6%. "This may seem high, but a score of 98% means that a site is not available for half an hour per day. This makes 14 hours a month, or a week a year", says Mark Pors, one of the founders of WatchMouse.

As a comparison to the US market, two "role models of e-commerce" - amazon.com and barnesandnoble.com - were monitored during the same period. Amazon`s performance was similar to that of the average European web shop, whereas Barns & Noble outperformed most e-commerce sites with an uptime of 100%.

The consequences of downtime are reflected not only in loss of income. Pors: "A website that is not available can cause stacks of work for your helpdesk and, at the end of the day, damage your brand. The problem is that many website owners are unaware that sites are responding poorly, or not responding at all. If they were aware of this, taking action to intervene is simplicity itself: for example, by adding extra server capacity."

WatchMouse has concluded from its survey that more than 70% of the web sites have not achieved optimum accessibility. Given the increasing trend in web site performance management tool purchases, gigantic sums are involved: Online sales will increase by 44% to €13 billion ($17 billion) in Western Europe over the holidays period, compared to €10 billion ($13 billion) in the US (Forrester Research, November 2004).

December is a top month for purchasing on the internet. Pors: "We see response times and the number of error reports increase dramatically in the days leading up to Christmas."

WatchMouse publishes first 'Site Availability Index' (2005-06-28)

Only 9 out of 25 funds listed on the Amsterdam stock exchange have sites with good availability

Of the websites of the 25 funds listed on the Amsterdam stock exchange (AEX), only nine display optimal availability. The availability of the other sites, including those of multinationals, ranges from poor to dramatically poor. Unilever has the best result of all websites, with an uptime of 99.995%. The site with the lowest availability is that of Wolters-Kluwer, with an uptime of 94.80%, which represents more than 37 hours of poor performance, or even unavailability, per month. This was the conclusion drawn from the first Site Availability Index created by WatchMouse, a company supplying monitoring services for websites and e-commerce applications world-wide.

An uptime of 99.9% is seen as the minimum acceptable level. This percentage is also often quoted in service level agreements (SLAs) with hosting providers. In order to determine the extent to which the sites of AEX funds achieve satisfactory uptime, WatchMouse monitored the sites for more than two months. Downtime was said to occur if a site was not available or did not respond within 8 seconds.

The Site Availability Index for AEX funds (www.watchmouse.com/bereikbaarheidsindex/2005/AEX.html) showed that only nine funds fulfilled the minimum required level of 99.9%. These were Unilever, Philips, AEGON, Numico, Akzo Nobel, ASML Holding, Kon. P&O Nedlloyd, Versatel and Buhrmann. Bringing up the rear were IT company(!) Getronics (96.87%), DSM (96.75%), and Wolters-Kluwer, which with a score of 94.80% is over a day and a half a month ‘off the air’.

The Site Availability Index for AEX funds is an initiative of Emerce and WatchMouse and will be repeated annually.

"Very surprised"

Mark Pors, chief technology officer at WatchMouse, stated that he was "very surprised" by the results. "With many sites, we found an uptime that is worse than that of many smaller companies. And this while AEX funds in particular should attach a great deal of priority to their corporate image. A maximum uptime is part of the 'brand performance'. Our theory is that, where there are a lot of people involved within an organisation, there are a lot of hands unplugging cables, so to speak. These companies have complex processes, a great many internal changes are made, and outsourcing of various activities means transparency is often at a premium. This is clearly the case with Getronics, for example. The uptime of the site at the weekend is 100%, but during the week, when people are working, this decreases dramatically."

Pors suspects that the popularity of the sites could also be a reason for poor availability. "Naturally, sites belonging to AEX funds get a lot more traffic than the smaller businesses. On the other hand, this is no excuse; if we look at large web site performance management tool brokers in the US, for example, all achieve an uptime in excess of 99.9%."

Meerderheid e-commerce sites kan komende kerstdrukte niet aan (2009-05-14)

WatchMouse voorziet wachtende e-shoppers

UTRECHT 20051201 -- Nu de decemberinkopen weer in alle hevigheid zijn losgebarsten, blijken veel web site performance management tool shops regelmatig 'gesloten' te zijn. Dat concludeert WatchMouse in haar jaarlijkse bereikbaarheidsonderzoek van cadeausites. Het Nederlandse sitemonitoringbedrijf heeft net als vorig jaar een onderzoek gehouden onder webwinkels. Slechts drie sites in het onderzoek haalden de maximale 100%. Het merendeel haalt zelfs niet de score die door hosting providers wordt aangehouden als absoluut minimum.

Veel sites zijn maar matig voorbereid op grote aantallen bezoekers. Door de grote belangstelling raken servers regelmatig overbelast. Ook blijken reactietijden van sites dramatisch dalen. Het onderzoek dat WatchMouse in de weken voor Sinterklaas heeft gehouden, laat duidelijk zien dat sites problemen vertonen naarmate er meer bezoekers in de webwinkels verschijnen.

Om te controleren of e-commerce sites goed bereikbaar zijn, heeft WatchMouse de hele maand november controles uitgevoerd. De uptime bleek regelmatig onder de 99.9% te liggen, een grens die in veel service level agreements (SLAs) van hosting providers geldt als minimum. Dat percentage wordt maar door tien van de 25 sites gehaald. Neckermann, Bonaparte en eBay zijn de enigen met een score van 100%. Vorig jaar waren er nog zes sites die een maximale uptime haalden.

De bereikbaarheid van Kijkshop, Bart Smit, de Bijenkorf en Wehkamp blijkt verre van optimaal. De score van Wehkamp, 97.27%, betekent bijvoorbeeld dat deze site per dag meer dan een half uur slecht bereikbaar is.

De grootste stijger was Bonaparte (kleding) die van de 17e plaats in 2004 steeg naar een gedeelde eerste plaats. eBay bleef als enige twee jaar achtereen op 1. De grootste daler was ECI die van een gedeelde eerste plaats in 2005 naar de 23ste plaats zakte.

In het licht van de toenemende bestedingen web site performance management tool kan de economische schade voor een site groot zijn. In de eerste zes maanden van dit jaar is er web site performance management tool ruim een miljard euro besteed, concludeert de Thuiswinkel Markt Monitor 2005. De web site performance management tool bestedingen maken met 37% ten opzichte van dezelfde periode vorig jaar bovendien een snelle groei door.

Consument gewend aan snelheid

"In vergelijking met vorig jaar zijn effectieve maatregelen uitgebleven", zegt Mark Pors, CTO van WatchMouse. "Consumenten zijn gewend aan snelheid op internet. Moeten ze wachten op een site, dan blijken ze zeker voor decembercadeaus gemakkelijk naar een andere site te gaan. Veel bedrijven weten echter niet dat hun sites matig bereikbaar zijn.”

Opvallend zijn verder de sites die 100% halen. Pors: “Twee van de drie blijken in het buitenland gehost te worden. Waarschijnlijk is men in de VS (eBay) en Duitsland (Bonaparte) wel gewend de sites goed te dimensioneren”.

Vorig jaar bleek de kerstperiode overigens nog drukker dan de periode voor Sinterklaas. Om die reden zal WatchMouse ook in de weken voor kerst blijven monitoren. Vlak voor kerst verwacht WatchMouse met de resultaten te komen van die tweede testperiode.

Het onderzoek liep van 1 t/m 30 november 2005. Van 'downtime' is sprake als een site een foutmelding geeft of de HTML na acht seconden niet ontvangen is, en dit vanuit een tweede meetpunt bevestigd is. Het complete bereikbaarheidsonderzoek is te vinden op: http://www.watchmouse.com/availabilityindex/2005/eshops_NL.php

What do you want to check with a service such as Watchmouse? (2005-01-31)

As I explained in my previous column, you can use a monitoring service in a number of roles. Common to all these roles is the fact that you are keeping alive some services for the benefit of your customers, suppliers, employees or partners. These users are, in the end, all that counts.

What are the objects that you should be checking? Obviously, the least you want to do is check the service that is most visible to these users. This could be the webserver, or a POP or FTP server for example. You would start by setting up a rule to check the server and a URL. The frequency with which you can monitor (that is: the elapsed time between checks) is typically limited by the type of subscription that you have. Only in specific cases would you not check as often as your subscription allows.

Note that there is a difference between a CONNECT on port 80 rule and a HTTP rule. The first just connects to the port that the webserver is supposed to use. The HTTP rule also checks whether the webserver can produce a valid HTTP response, and whether the document can be found. You probably want the latter check.
Similar reasoning applies to POP and FTP checks. If you set up two different rules on the same host, this allows you to distinguish for example between a broken webserver and a host that is down. If you want even more content oriented checks, have a look at the so-called PLUG-IN rules. Additionally, you can set up checks to make sure that your users are actually using the services that you intend them to. The whole Internet depends heavily on the domain name system(DNS) functioning correctly. If it does not work properly your users may be directed to another site than you intended. This could be a configuration error, but it could also be a defamation hack. In either case, you want to know.
First of all you want to check whether the root servers of the Internet accurately find the DNS that is serving you. This can be checked with a DNSNS rule. What you are checking with this rule is whether the registrar's databases are correct. Second, you want to check if that DNS server (and its slaves) are serving up the proper IP address for the server. For this you can use the DNSA rule, and it will warn you if the DNS server is not working or serves up the wrong address. (Note that the hosting party can change that address at its discretion, as part of a renumbering operation for example.)

Who should you notify of rule failures? Again, different roles have different information requirements. You want to notify the person who can fix things as soon as possible. Mail or SMS/text them directly, you do not want to be in the loop. You might set up an web site web site performance management tool management tool chain, which fires off after a certain amount of errors. Note: make sure that you send the message on a channel that is not affected by the outage: if your e-mail system does not work, delivering a message to that effect should not depend on that e-mail system.
The people in charge of overseeing somebody else's service levels should only get web site web site performance management tool management tool messages, if at all. Rather, they should get the weekly or monthly service reports.

Why do you need a monitoring service such as Watchmouse? (2005-01-31)

There are a number of reasons for this, depending on your role in your organization, and what you want to achieve. Each of these roles leads to a different approach for using and setting up the service.

Most likely you are either responsible for keeping a service such as a website online, or you have contracted somebody else to do that for you. Additionally, you could be a consultant or technical architect who wants to get an insight in web site performance management tool and uptime characteristics of various solutions and services.

If your role is to keep things running, you really want to be notified of problems as soon as possible, before your customers or supervisors notice. You want appropriate error messages and not too many false alarms. As you configure Watchmouse you probably want to have a quick alert by e-mail or SMS/text message when things don't work and have additional diagnostic information web site performance management tool. In this way, downtime can be kept to a minimum. It is not only the quality of the systems that counts, but also the speed with which you can fix problems.

Your role could also be in overseeing your service providers, whether they are internal or outsourced. In that case, you don't want to be interrupted by these messages, unless the situation becomes dramatic. Instead you would like to look at the weekly report, and see if your service providers are living up to their promises. On the Internet it is easy to get 99% uptime, and you should really be doing better than that. The services that regularly fail to make this grade need attention, to see if another approach to provisioning them works better.

If you are considering technical alternatives for the way you are setting up your e-business, you are most likely interested in typical failure modes. For example, we know from experience that most website problems are software problems, followed by sizing problems. Communications problems are fairly rare, and if they occur they take the form of peering problems: websites cannot be reached from specific networks, even if all networks are operational. One approach using Watchmouse reports is to check various aspects with different rules. Use one rule to download the homepage, another to check the DNS and a third to check connectivity to the hosting centre. In a next column I'll go into the details of this.

Independant, external testing (2005-10-15)

I started to work at Q-go in 2000. Q-go provides companies with self service pages on the Internet. Their customers ask a question in their own language and wording, and immediately get a very relevant answer. The power of the Q-go solution is its natural language technology, which enables it to understand the questions. The Q-go solution is offered as a hosted (ASP) solution, which of course has to work 24 x 7, a new area for me at that time.

At my previous jobs, at universities and research institutes, this was different. We worked from eight to six. If a demo application didn't work, the users just called, and we fixed the problem. And at six, we stopped and went home. All customers and other relations went home too. A nightly malfunction in the server was no problem, as there was no customer there to notice the problem.

At Q-go, this is completely different. A service should be web site performance management tool all the time. Day and night. Initially there were no tools to test whether our service was web site performance management tool or not. The only way to test it was to use the application itself. And so I did. During the day, but also at night, I checked whether the application was up. Our customers use the Q-go application continuously, and notice immediately when the application fails. Customers would call me in those cases, and it's not very pleasant to hear from your customers about an issue with your service.

So we developed some solutions ourselves to hear before our customers when something was wrong. And to be able to react to problems quickly. But customers kept calling!

How was that possible? Closer investigations revealed that the test system used the same resources (computers, networks, name servers) as the system under test... The test were not performed properly in case of problems. The text-alerts (SMS) did not reach us either. The cause was identical: we used the same hardware, the same network, and the same power (!) as the systems we tested.

My lessons learned:

• Keep the systems that test completely separated from the systems you test.
• Test your services (web servers, mail servers, ...) from the point-of-view of its users: the customer on the Internet.
• Don't forget regular maintenance of your test systems (software and hardware) after the installation!

For me, I'm outsourcing external testing!

Online shops, speed and downtime, getting the facts. (2009-12-07)

These days your website plays an important role in informing potential customers, converting them into customers who want to do business with you, and possibly also conducting the transactions with these customers. In other words: Your business relies ever more on the digital economy, and increasingly on the transactional part of it, the online shop.

These online shops should obviously provide satisfactory web site performance management tool. Here, both the speed at which they serve pages and their uptime are important. If potential customers cannot reach the online shop, or the online shop is too slow, they are less likely to do business with you now, and in the future. Studies have revealed that half of the people who experience downtime on a website go to its competitor. A majority of online shoppers say web site performance management tool and uptime influences their choice of online shop.

The amount of revenue that is lost when your website or online shop does not behave properly is hard to quantify. If your website is slow your customers may select a distribution channel that is more costly for you, or they may go to your competitor. Even worse, they may complain about your company to other potential customers. All of this boils down to lost revenue.

A good website is up for at least 99.9% of the time, even though this still represents more than 8 hours in a full year. In a recent survey we found that many websites do not even achieve 99% availability, which corresponds to more than 3 days of downtime a year. As regards speed, if a web page does not load in less than 4 seconds, people start to leave the site, sometimes forever.

How do you make your online shop an efficient experience for your customers? The site must be designed with a strong focus on the customer task. The technology must be no more complex than is relevant. People get annoyed by slow loading Flash intros and complex and slow Flash-based navigation. Take a look at the Google home page; it is one of the fastest websites in the world. On the other hand, you can still use a video clip of a product, if that is relevant to the customer at a particular point in the transaction. You can also use advanced Web 2.0 technology if it makes the user interface more resilient and user-friendly. To experience this, look at Google maps using a dial-up internet connection. It is a really complex user interface, but everything possible has been done to create a positive user experience.

Technology is also important; make sure that you have good service level agreements with all your technology providers. You also want to stress test the site, to see what happens if a lot of people start using it simultaneously. Finally, you should independently monitor the site. When it is time to talk to your hosting company, IT department or website maintainer, it is very helpful to have hard data that reports on the speed and uptime of your online shop.

Website web site performance management tool is the key to customer satisfaction (2007-06-27)

How often have you typed in the Google URL and received a page that will not load? I am willing to bet that this is a rare occurrence. Despite its busy traffic, Google is a textbook example of a web site that has almost perfect web site performance management tool and therefore serves a great number of satisfied customers. The market share of the search engine is a resounding confirmation of this. You are assisted quickly, so you come back sooner. Research conducted by JupiterResearch has revealed that visitors to a site only have 4 seconds of patience. If the site has not been loaded by that time, they leave. Error messages also prompt potential customers to go to the competition.

Why do organisations still devote so little attention to the effective availability of their site? Performance is the key to satisfied customers. For many companies, their web site is the face of the organisation. Consumers and also business users of the Internet use the wealth of information on the web to compare purchasing options. It is of immeasurable importance that they are also actually able to find what they are looking for. If this is not possible at one company, competitors are straining at the leash to offer their services through a correctly functioning site.

Coming back to the praise that we had for Google, we see that the search engine has made significant investments in the availability of its web site. The page is run by several machines at various sites. If one crashes there are enough back-up servers that can take over the traffic flows to guarantee optimum web site performance management tool. In addition, the search machine invests a great deal of time and money in the right hardware and people. Although the site has a difficult task – searching through an index of billions of documents – it is almost always web site performance management tool and loads fast.

The actual site is unspectacular in construction. This applies to the majority of sites with a high level of availability. Simple sites such as the news site NU.nl are almost always easy to access. Nevertheless, it is not only the layout of the site that determines how the web page performs. Too many photos, long symbols and frills make web sites slower to respond. The fact that the ‘back end’ of the site is not efficiently programmed also contributes to longer loading times. Frequent consultation of background databases is also detrimental to the speed of the page.

Where it often goes wrong is when different people are working on a site, thereby disturbing the links between the various elements. The different parts of the site will work correctly, but the site as a whole will fail to perform. This means long waiting times for people who want to use the services of a company.

Service providers at the upper end of the market are becoming increasingly aware of this. The contracts that they use frequently include a service level agreement (SLA) for the part for which they are responsible. Nevertheless, they regularly make mistakes due to the fact that the promised web site performance management tool is not subsequently verified (by an independent party). Although it is now essentially part of the contract, there is insufficient actual verification. Ideally, web site web site performance management tool should become a permanent component of a contract. In addition, clear internal agreements must be made on who has final responsibility for the efficient loading and availability of a site.

Regular testing is also essential for the facilitation of good availability. This will prevent a great deal of errors, keeping the site up and running at crucial times. The storm that blew over the Netherlands at the end of January was a good opportunity to see which sites were prepared for extreme loads and which were not. The site of the Dutch weather institute, KNMI, was almost unreachable, while some logical thought could have protected them from this eventuality. If you know that a major storm is heading towards the country you can be sure that people will search for information on the weather and roads on the Internet. Sites such as those of KLM and Schiphol were also unreachable, while the specially created site Crisis.nl, which had been kept as simple as possible, was able to serve a large number of people.

Including ‘stress tests’ in a SLA or conducting them regularly in-house is therefore to be recommended. Companies can easily take control by ensuring that their service provider executes this type of test or by putting their own site under pressure. This is the best method of checking whether your web site can handle a sudden increase in visitor numbers. It is also good to know whether the servers on which your site is running actually ensure that your page is always web site performance management tool and loads correctly. For companies, it is crucial to see when they are off air. This can save them a large amount of money every year and will also reduce the number of irritated visitors to the site. This is how you keep customers satisfied and keep the company running.

phpDirectorySource SQL Injection and Cross Site Scripting Vulnerabilities (2009-07-24)

phpDirectorySource is prone to an SQL-injection vulnerability and a cross-site web site performance management tooling vulnerability because it fails to sufficiently sanitize user-supplied data.

Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

Mozilla Firefox/Thunderbird JavaScript Engine Memory Corruption Vulnerabilities (2009-07-24)

Mozilla Firefox and Thunderbird are prone to multiple remote memory-corruption vulnerabilities that affect the JavaScript engine.

An attacker can exploit these issues to corrupt memory on the affected computer and run arbitrary code in the context of the user running the affected application. Failed exploit attempts will cause denial-of-service conditions.

These vulnerabilities were previously covered in BID 35758 (Mozilla Firefox MFSA 2009-34, -35, -36, -37, -39, -40 Multiple Vulnerabilities) but have been assigned this record to better document the issues.

RaidenHTTPD Cross Site Scripting and Local File Include Vulnerabilities (2009-07-24)

RaidenHTTPD is prone to local file-include and cross-site web site performance management tooling vulnerabilities because the application fails to properly sanitize user-supplied input. These issues affect the WebAdmin component.

An attacker may leverage the cross-site web site performance management tooling issue to execute arbitrary web site performance management tool code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

Exploiting the local file-include issue allows remote attackers to view and subsequently execute local files within the context of the webserver process.

RaidenHTTPD 2.0 build 26 and prior versions are affected.

PowerDNS Recurser Buffer Overflow Vulnerability (2010-01-09)

PowerDNS is prone to a remote buffer-overflow vulnerability because it fails to properly bounds-web site performance management tool user-supplied input before copying it into a fixed-length buffer.

Successfully exploiting this issue allows a remote attacker to execute arbitrary code with superuser privileges, resulting in a complete compromise of the affected computer. Failed exploits will cause a denial of service.

8E6 R3000 Internet Filter Multiple Cross-Site Scripting Vulnerabilities (2007-05-29)

The 8E6 R3000 Internet Filter appliance is prone to multiple cross-site web site performance management tooling vulnerabilities because it fails to properly sanitize user-supplied input.

An attacker may leverage these issue to execute arbitrary web site performance management tool code in the browser of an unsuspecting user in the context of the affected device. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

Specific information on affected firmware and model number is currently unavailable. This BID will be updated as more information emerges.

Linux-based websites 'perform better' (2010-01-13)

Linux-based websites perform better than those hosted on Windows servers, according to research.

WatchMouse, a Dutch firm that monitors server web site performance management tool, based its research on a survey of over 1,500 European websites. The company says that, although the websites it surveyed were more frequently based on Microsoft's IIS web server platform running Windows than on Apache running Linux, the latter option performed better in terms of both uptime and load time.

Facebook: Slow And Unresponsive? (2010-01-13)

Contrary to a recent study that showed that Facebook is among the most reliable social networks, new study conducted by WatchMouse shows abysmal results for Facebook. 104 sites were monitored by WatchMouse, and Facebook was by far the worst web site performance management tool-wise: it had slow loading times and frequent errors. Check out the graph (too big to show here) to see how bad it looks.

Euro 2008 losers are actually web site winners. (2010-01-13)

France may have left Euro 2008 with its tail between its legs after a humiliating defeat by Italy, but the country still topped the league when it came to having the best sporting web site. For what little consolation that brings.

WatchMouse, a website web site performance management tool monitoring outfit, carried out its own nailbiting tournament to find the Euro 2008 nation with the best sport website by fashioning an index which takes into account three parameters; errors, speed (load time) and availability.

Facebook tops one list of 'slow and inaccessible' social networks (2010-01-13)

On Thursday, Web site-monitoring firm WatchMouse released the results of a study about the web site performance management tool of 104 social-media sites--social networks, blogging communities, bookmarking sites, and the like--and boldly deemed them to be overall "slow and inaccessible."
