In the final month of 2009, Swishmail, iWeb Technologies and WestHost had the most reliable hosting company sites. All three sites responded to all but one of Netcraft's requests throughout December.

This is Swishmail's second consecutive appearance at the top; last month, it shared the glory with Verio. Swishmail's website is served by nginx on FreeBSD. This New York based company specialises in business email hosting, but also offers several web hosting plans, all of which include access to a webmail client and shared calendars.

iWeb Technologies' website is hosted on a Linux server in Canada, and offers dedicated, shared and colocation hosting as well as domain registration services. The company recently announced an annual revenue increase from $15M to $27M.

WestHost also uses Linux for its main site and hosts more than 70,000 other websites. Their services include shared web hosting, dedicated servers, reseller hosting and domain name registration. WestHost was acquired by UK2 Group in 2008, but continues to offer services under its own name.

Six of the most reliable hosting company sites in December were running Linux, and two were using FreeBSD. Netcetera once again provided the only Windows presence, with its site being served by Microsoft IIS 6.0 on Windows Server 2003.

Netcraft measures and makes available the response times of fifty leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.

From a customer's point of view, the percentage of failed requests is more pertinent than outages on hosting companies' own sites, as this gives a pointer to reliability of routing, and this is why we choose to rank our table by fewest failed requests, rather than shortest periods of outage.

Further information on the measurement process and current measurements are available.

For October SingleHop and Acens had the most reliable hosting company sites.

SingleHop, who in October went skydiving to celebrate a 19.5% revenue increase over the second quarter of 2009, came joint first by responding to all of Netcraft's requests. SingleHop's main site runs PHP and uses Apache on Linux.

Acens joined SingleHop at the top of the table in October. This is the second time Acens has been in the top spot this year, the other being in March. Acens is a Spanish hosting company that was set up in 1997. Like SingleHop, Acen's website is powered by PHP on an Apache sever and Linux operating system.

INetU narrowly missed out on first place this time, but has been in the top ten for nine out of ten months this year. INetU's homepage is powered by PHP and runs on Apache. In October's top ten most reliable hosting companies seven are running their website on Linux, one Windows Server 2008 and one FreeBSD.

Netcraft measures and makes available the response times of fifty leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.

From a customer's point of view, the percentage of failed requests is more pertinent than outages on hosting companies' own sites, as this gives a pointer to reliability of routing, and this is why we choose to rank our table by fewest failed requests, rather than shortest periods of outage.

Their site is powered by ASP.NET and uses IIS 7.0 on Windows Server 2008. The company achieved Microsoft Security Solutions Competency earlier this year, which is their fourth competency within the Microsoft Gold Certified Partner Program.
