May 2011 Web Server Survey

In the May 2011 survey we received responses from 324,697,205 sites.

Apache exhibited by far the largest growth this month, gaining 12.5M hostnames and over 1.5 percentage points of market share. SoftLayer saw the largest increase, gaining 3.0M hostnames, while Earthlink took a big drop, losing 1.3M.

Microsoft only gained 0.8M hostnames this month, losing them half a percentage point of market share. Rackspace and GoDaddy both showed notable growth, 260k and 280k respectively, but Intergenia AG suffered a fairly big loss of 1.1M hostnames at server4you.net in the US.

nginx and lighttpd both saw small gains of 381k and 21k respectively, while Google gained a much larger 1.5M hostnames.

The Tōhoku Earthquake has not caused any significant drops in the number of sites seen by the survey, though Japan's growth this month of 231k hostnames was about two thirds of what was seen in March (345k) and April (389k).

In Libya, where most of the country's internet access was cut off in early March, hostnames have dropped by about 95% from 917 to just 42. The recent mass protests and political turmoil experienced by other North African and Middle Eastern countries, such as Tunisia, Egypt and Syria, has not yet resulted in any noticeable changes to the countries' hostname numbers.
