February 2005 Web Server Survey Finds 40 Million Sites on Apache

In the February 2005 survey we received responses from 59,100,880 sites, an increase of 906,044 sites from last month.

This month's survey marks a significant milestone for Apache, which now serves more than 40 million sites. The open source Apache server reached 10 million sites in June 2000, 20 million in November 2001 and 30 million in November 2003. Apache was detected on 658 domains in the initial Netcraft survey in August 1995, when its 3.5 percent market share was dwarfed by software from NCSA (57 percent) and CERN (19.7).

Apache seems to have regained momentum in its ongoing battle for market share with Microsoft. After nearly no change in server market share in 2004, Apache extended its lead over Microsoft by 1 percent last month and another 0.4 percent this month, and now runs on 68.8 percent of web sites, compared to 20.9 percent for Windows servers.
