Rackspace and , New York Internet are the most reliable hosting companies for May 2007, followed closely by DataPipe, Verio, GoDaddy and Kattare.

With this month's results, Rackspace and New York Internet continue to reinforce their track records as industry leaders in reliability. Rackspace, a managed hosting provider based in San Antonio, Texas led our monthly reliability survey six times in 2006 and twice thus far in 2007. On May 23 the company announced $70 million in financing to support future hardware purchases and expansion of its data center network. New York Internet, a colocation specialist in New York's financial district, makes its 10th appearance atop the leaderboard since 2003.

iPowerWeb is ninth in the May rankings with no downtime, but experienced a major outage yesterday, which affected customer sites as well as the company homepage.

Three of the 10 most most reliable hosts run their web sites on Linux, two on Windows, three on FreeBSD and one on Solaris.

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 customers’ point of view, the percentage of failed requests is more pertinent than outages on the 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.
