April 2003 Web Server Survey
The Netcraft Web Server Survey is a survey of Web Server software usage on Internet connected computers. We collect and collate as many hostnames providing an http service as we can find, and systematically poll each one with an HTTP request for the server name.
In the April 2003 survey we received responses from 40,100,739 sites.
