January 2007 Web Server Survey

In the January 2007 survey we received responses from 106,875,138 sites, an increase of 1.63 million from last month's survey. Leading the growth is Microsoft, which adds more than 650K hostnames on its Windows Live Spaces blog service, while Go Daddy (+165K) and Google (+105K) also had growth of more than 100,000 sites this month.

Windows improve its share of the market for web server software, gaining 0.1 percent while Apache slips by 0.5 percent this month. Windows added 620K hostnames, while Apache had growth of 492K sites. Microsoft's gains were more pronounced in active sites (hostnames that contain content and likely to represent developed web sites), where its share is 0.88 percent higher and now approaching 35 percent, compared to 59 percent for Apache.
