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.

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