August 1st - 31st 2005
Datapipe, Rackspace and Tiscali share the top slot as as the most reliable hosting company sites this month. The results continue a string of exceptional performances by Rackspace and Datapipe, both in 2005 and over the longer haul.
Rackspace, a managed hosting provider based in San Antonio, Texas, has been the top performer in five of the past seven months. The company's web site, which runs on Linux, has not had a measurable outage since March of 2004. Datapipe, a managed hosting provider in Hoboken, N.J., has been the best performer twice in 2005, and was the most reliable hosting company for the second half of 2004. The Datapipe web site, which is hosted on Windows Server 2003, has not had a measurable outage since Necraft began public reporting of monthly uptime performance in June 2003.
In August their performance was matched by Tiscali, a pan-European provider of hosting and Internet access services. This month marks Tiscali's first time as the most reliable hosting provider. Tiscali's site runs on Linux, which dominates with five of the top 10 hosters, with 2 on Windows, 2 on FreeBSD and 1 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 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.
