Monitoring Hosting SLA

Even website hosting companies have too little uptime (2007-02-05)

Leaseweb, Rackspace and WideXS score well

Utrecht, 5 February 2007 – Research carried out by WatchMouse, the Dutch site and server monitoring company, has revealed that many website hosting companies are not achieving optimum performance in terms of uptime. During the months November and December 2006, the company registered the average loading times and availability of the sites of eleven website hosting companies. Leaseweb, Rackspace and WideXS came out on top.

The three best-performing companies all had an average uptime of 99.99% or higher. A good score, says WatchMouse, although the company pointed out that, even when achieving this score, a site will still be unavailable for eight hours every year. The reasons for this downtime vary between sites, although problems with the name server (DNS) and excessive loading times dominate. The types of problem also differ from site to site, indicating that good choices – for example for DNS solutions – are essential.

Companies which scored 99.7% or less are at risk of losing clients annually owing to their site loading too slowly, or unavailability of the web page. Four of the eleven hosting companies scored below this limit and will therefore have to work on their availability. Nevertheless, the organisations tested generally performed better than the average bank website, for example.

"On the one hand, it is reassuring to see that website hosting companies recognise the importance of good availability. Nevertheless, there is room for improvement, particularly as it is precisely these companies that should be setting the pace", says Mark Pors, Chief Technology Officer at WatchMouse. "Customers looking for a web hosting company will not want to entrust the management of their site to a hosting company whose own site is unreliable. Optimum performance is therefore crucial, for these companies in particular."

LB Icon chooses WatchMouse for independent website monitoring (2005-01-31)

Customer websites verified from the visitors' perspective

LB Icon and WatchMouse have signed a contract for the continuous monitoring of the websites and services of LB Icons' customers. Using the WatchMouse services, LB Icon expects to raise its service level even higher.

The Application Management & Hosting Services (AM&HS) group of LB Icon maintains the administration and management of servers and applications of a large number of (international) clients. This makes AM&HS responsible for the performance and availability of the websites and Internet applications.

Using the WatchMouse services, AM&HS will instantly be aware of upcoming and/or acute incidents related to the websites of its clients, and can, as a result, resolve problems in a short time frame.
The websites and their functionality are checked for accessibility, speed and conformance from different locations around the world. Because the websites are checked in the same way that visitors are experiencing them, incidents will be detected at an early stage. Also, using WatchMouse's objective periodical reports, it is possible to see if the performance is in accordance with the agreed service levels (SLAs).

Eveline Aendekerk, MD a.i.: "The door of a shop should never be jammed, websites and the functionality on those sites should simply be accessible and available. Our clients should be able to rely on this completely, so they can focus on their primary business processes, such as communication, interaction and sales.
We chose WatchMouse because of their expertise, and also because of the simplicity and user-friendliness of their system and services".

Stan P. van de Burgt, one of the founders of WatchMouse: "I find it a powerful gesture that LB Icon doesn't just monitor the websites of their clients, but that they selected an external party for this, and on top of that give their clients access to the results. Many companies where the website plays an essential role in business, don't have any awareness of this. They have no idea of the risks and the resulting damage, until the day comes that things actually go wrong"

Spanish websites suffer from poor performance (2005-12-04)

WatchMouse research shows that 71% of IBEX websites availability is below industry standards

MADRID, 20051121 - Of the top 35 funds listed on the Bolsa de Madrid (IBEX), 25 have websites with poor to dramatically poor availability. Many of the sites are badly accessible or unavailable for more than an hour per month.

The worst site, that of Antena 3 TV, is even unavailable for an equivalent of more than 8 days per month.

This was the conclusion drawn from the first Spanish Site Availability Index created by WatchMouse, a company supplying monitoring services for websites and e-commerce applications worldwide. In order to determine the extent to which the sites of IBEX funds achieve a satisfactory uptime, WatchMouse monitored the sites continuously between October 23 and November 11, 2005. Every five minutes, one of WatchMouse’s test stations tried to access the homepage of the site, which was expected to download within 8 seconds, without any errors.

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. There were only five sites which achieved perfect 100% availability - Sogecable, Arcelor, FCC, BSCH and Altadis. The availability of the three worst performers was less than 95%; Acerinox (94.66%), Gamesa (86.54%) and Antena 3 TV with 73.05%.

Mark Pors, chief technology officer at WatchMouse, stated that he was "very surprised" by the results. "With several sites, we found an uptime that was worse than that of many smaller companies. This is worrying as IBEX funds in particular should give a great deal of priority to their corporate image. Maximum uptime should be part of the overall 'brand performance'."

Pors suspects that for some sites, the popularity could be a reason for poor availability. "Some of the sites belonging to IBEX funds will get a lot of traffic. However, this is no excuse; if we look at large online brokers in the US, for example, all achieve an uptime in excess of 99.9%."

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 performance 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 available. 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.

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 escalation 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 escalation messages, if at all. Rather, they should get the weekly or monthly service reports.
