Rackspace Most Reliable Hosting Company Site during February

Rackspace, New York Internet, Verio and Pair Networks ranked as the most reliable hosters during February 2005. Rackspace, a managed hosting specialist, has made numerous appearances in the monthly top 10, but this is the first time it has been the top performer. Making its first appearance is domain registrar Go Daddy, which was highly reliable during a period of heavy site traffic related to a Super Bowl advertisement.

This month's top 10 includes four sites running on Linux, two on Windows Server 2003, three on FreeBSD and one on Solaris 8. A Linux site was the most reliable for the first time since June 2004, ending a string of months in which either FreeBSD or Windows Server 2003 powered the top performing site.

Netcraft measures and makes available the response times of fifty leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from eight 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.
