In the January 2005 survey we received responses from 58,194,836 sites, a robust gain of 1.27 million sites from the December survey.
After months of little change in market share between the two major web servers, Apache added nearly a full percentage point to its lead over Microsoft, which is now 47.5 percentage points (68.4% to 20.9%) as measured by hostnames, with a slightly smaller gain in active sites.
While this month's 1 percent shift is modest by historic standards, it follows a 12-month period in which Apache's lead grew by just 0.09 percent (from 46.56 to 46.65%), despite adding 7.6 million sites between Dec. 2003 and Dec. 2004. Microsoft added 2.46 million sites during the same period.
