In the September 2004 Netcraft's Web Server Survey responses from 54,407,216 sites were received. The prevailing trends continue - rapid Internet growth of more than 1 million sites a month, and little change in market share among the leading web servers.

The static nature of the web server market is news in itself. The market shares for Apache and Microsoft have shown little change since November 2003, when shifts by domain registrars Register.com and Network Solutions contributed to a 2.8 percent one-month share gain for Apache. That is the longest period of market share stability in the history of our survey, as illustrated by our long-term trends graphic.

The trend remains intact despite the Download.Ject security event in June, which affected sites running Microsoft IIS 5.0 on Windows 2000. The incident appears to have spurred upgrades from Win2K to Windows Server 2003, rather than any noticeable shift toward Apache.
