September 2009 Web Server Survey

In the September 2009 survey we received responses from 226,099,841 sites, reflecting a modest rise of 149 thousand sites.

Taking the limelight this month is nginx, which gained 1.2 million sites, beating Apache's growth of 823 thousand. The popular Russian social networking site Vkontakte is the most popular nginx site appearing in Netcraft's million busiest sites. Other popular nginx sites include the comedic Fail Blog and I Can Has Cheezburger? sites, which are both WordPress blogs owned by Pet Holdings, Inc.

lighttpd suffers a significant loss this month, in stark contrast to its impressive growth last month which took its total up to more than two million sites. lighttpd has lost more than half of its sites since last month leaving its new total at 844 thousand. This drop was mainly due to the loss of 1 million sites on the tubely.com domain, which were hosted on the Amazon AWS service.

lighttpd promotes itself as a fast web server suitable for Web 2.0 sites like YouTube, Wikipedia and Meebo, with an event-driven architecture optimised for high performance AJAX applications.
