In the February 2007 survey we received responses from 108,810,358 sites, an increase of 1.93 million from last month. Apache has a decline of 442K sites this month, and sees its share of the web server market slip by 1.47 percent to 58.7 percent. This is the first time Apache's market share has been below 60 percent since September 2002.
Microsoft-IIS gain 935K sites, continuing an advance that has seen Microsoft steadily chip away at what once seemed an insurmountable lead for Apache. In our Feb. 2006 survey, Apache held 68% market share, giving it lead of 47.5% over Windows (20.5% share). In this month's survey, Microsoft's share has improved to 31.0%, narrowing Apache's advantage to 27.7%.
