April 1st - 30th 2006
Rackspace is the most reliable hosting company site this month, followed by Datapipe and iNetU. Rackspace was perfect this month - it experienced no downtime, and not a single failed DNS request was seen from any of our monitoring points during April. This marked the first flawless month for a host since Datatpipe did it in January 2005, while German host Komplex had a faultless month in March 2004.
This month's top three hosts have consistently been among the strongest performers in our Most Reliable Hoster surve. Rackspace was the most reliable host six times in 2005, compared to four times for Datapipe. INetU made the top 10 six times last year, and was the most reliable host for the second half of 2003.
Three Linux sites are found in the top 10 this month, three on FreeBSD, two on Windows and two 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 six 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.
