April 1st - 30th 2007
The three leaders each had a perfect month, with no downtime and no failed requests for their corporate sites during an entire month of monitoring from eight locations around the globe. Rackspace continues to build upon its stellar uptime performance, having finished at the top of the survey six times in 2006. On April 30 the San Antonio-based managed hosting provider reported record 2006 revenues of $224 million, a 61 percent improvement over 2005. Rackspace said it added more than 3,000 new customers in 2006.
This marks the first time that either Easynet or Easyspace have been the most reliable host in our monthly performance tracking. Easynet is a pan-European managed hosting provider with operations in the UK, Belgium, Germany , France, Italy, Spain and Switzerland. Easyspace is the web hosting arm of the iomart group plc, a UK internet services specialist.
Three of the 10 most most reliable hosts run their web sites on Linux, four on Windows and two on FreeBSD.
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.
Fuller information on the measurement process and current measurements are available.
