Rackspace and Tiscali Most Reliable Hosters in October

Rackspace and Tiscali are the most reliable hosting companies for October 2006, followed closely by Jumpline, WestHost, the UK's Demon Internet and Germany's Deutsche Telekom. Jumpline is based in Columbus, Ohio and focuses on the virtual dedicated server market, while WestHost is a Utah provider offering shared hosting.

Industry-leading reliability has become business as usual for Rackspace, a managed hosting specialist based in San Antonio, Texas, which finishes atop our monthly survey for the sixth time in 2006. Tiscali, an Italian company providing a broad range of hosting and domain services, was previously the most reliable host in May of this year and August 2005.

Five of the 10 most reliable hosters run their sites on Linux, while three use Solaris, two run on FreeBSD, and Windows hosts are shut out of the top 10 this month. The strong showing for Solaris includes two hosts (Demon, Deutsche Telekom) running Solaris 9/10 and one (Verio) on Solaris 8.

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.
