August 2004 Web Server Survey

In the August 2004 survey we received responses from 53,341,867 sites, a gain of more than 1.2 million sites from July. The August increased marked the sixth time in the past year that the survey has shown a monthly gain exceeding 1 million sites. In the last 12 months, the Internet has grown by 10.2 million hostnames.

Market share remained steady among major web servers, with Apache making modest gains of 0.3 percent in hostnames and just under 0.2 percent in active sites. Microsoft's market share remains steady in the wake of a security event in June connected to Microsoft-IIS 5.0. As was noted last month, previous headline-grabbing worms and security events have had little direct impact on web server market share.
