November 2004 Web Server Survey

In the November 2004 survey we received responses from 56,115,015 sites. The Internet has grown by 10.1 million sites in the first 11 months of the year, including a gain of 726,549 sites last month.

Barring a precipitous slowdown, 2004 should wind up as the Internet's second-strongest year for numerical growth, trailing only 2000, when the survey added 16.1 million sites. The survey added 10.6 million sites in 2001 and 10.4 million in 2003, marks that are well within reach given the pace of monthly gains thus far in 2004.

Prevailing trends continued apace in market share for major web servers, with the percentages for Apache and Microsoft fluctuating only slightly, as each continue to add users. Whle there has been some shifting between Microsoft operating systems (primarily upgrades from NT4 and Windows 2000 to Windows Server 2003), the competitive balance between Microsoft and Apache remains static.
