Rackspace and ZeroLag Communications are the most reliable hosting company sites for September 2008. These are the only two sites that responded to every request made by Netcraft's performance collectors throughout the month.

Rackspace specialises in managed hosting and is well known for its promise of Fanatical Support. This is Rackspace's first appearance at the top spot this year, but the company also featured within the top ten for three months in a row between April and June.

ZeroLag Communications states that it uses high-performance technology to deliver hosting solutions for businesses who don't want to wait.

Besides offering virtual hosting, dedicated servers and colocation, ZeroLag also provides T1 and T3 internet connections, web development services and security consulting. This is also ZeroLag's first appearance at the top spot this year, having made it into the top 10 in both June and July.

Last month's most reliable hosting company site, Hurricane Electric, appears in 7th place this month.

Both Rackspace and ZeroLag Communications run Linux on their main sites. Two other companies within the top ten also use Linux, while green.ch uses F5 BIG IP and pair Networks uses FreeBSD.
