May 2009 Web Server Survey

In the May 2009 survey we received responses from 235,890,526 sites, an increase of 4.3 million on last month. Apache remains firmly in the lead, having gained 3.3 million sites, and Microsoft-IIS remains second, having lost almost 0.9 million (mostly due to less activity seen at accounts on Microsoft's own Live Spaces service). QQ.com, the popular IM service in China, remains third with 29M sites. Google takes fourth place, after gaining approximately 1.5 million sites, and remains ahead of nginx which gained 200,000.
