April 2011 Web Server Survey

In the April 2011 survey we received responses from 312,693,296 sites, a growth of almost 14.7M hostnames. This is the tenth consecutive month of growth seen by the survey.

As in recent months, Apache contributed most to the increase, gaining 11.4M hostnames. Especially large increases were seen at AmeriNOC, SoftLayer and ServerInt, which saw gains of 3.7M, 2.5M, and 1.2M hostnames respectively. Large increases were also seen at several hosting companies, including Amazon, China Telecom and BurstNET.

Microsoft saw an overall increase of 1.2M hostnames, with the largest growth seen at Go Daddy. Microsoft's largest loss was due to the continuing movement of Windows Live Spaces to WordPress.com.

This month saw nginx gain 651k hostnames overall, despite losses at ServePath, China Telecom and Amazon. The largest increase was seen at Hetzner Online AG which saw an additional 349k sites.

The Tōhoku Earthquake did not cause a drop in the number of sites seen by the Web Server Survey this month, as the data collection completed before the earthquake struck.
