February 2004 Web Server Survey

In the February 2004 survey we received responses from 47,173,415 sites.

The number of responding sites is up by over one million from January; however the percentage share between the different web servers is little changed, with Microsoft's half a percent drop in active sites being the most salient point of interest.
