June 1st - 30th 2005
Rackspace, Interland and 1and1.com share the top slot as as the most reliable hosting company sites this month. Rackspace, was also the most reliable hoster in February, March and April 2005. Datapipe, which was the most reliable performer for the second half of 2004, has now been among the top 10 performers every month thus far in 2005. This month's results end a string of nine consecutive appearances for iNetU among the top 10 most reliable hosts.
This month Linux, Windows and FreeBSD all have 3 sites each in the top 10, with one running Solaris. The second-place showing by Interland continues a string of strong performances for Windows 2000 hosts, which have ranked either first or second in reliability in each of the past three months.
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.
Fuller information on the measurement process and current measurements are available.
