July 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 July 2003 survey we received responses from 42,298,371 sites.

SunONE's significant increase of 254,603 sites is primarily attributable to Network Solutions' migrating around a quarter of a million parked sites back to a Solaris platform. NSI originally ran its domain parking system on Solaris, but moved large numbers of parked domains to a Microsoft-IIS system hosted at Interland over a year ago. NSI still hosts a significant number of parked sites at Interland.

SunONE is the sum of sites running iPlanet-Enterprise, Netscape-Enterprise, Netscape-FastTrack, Netscape-Commerce, Netscape-Communications, Netsite-Commerce & Netsite-Communications.

Microsoft is the sum of sites running Microsoft-Internet-Information-Server, Microsoft-IIS, Microsoft-IIS-W, Microsoft-PWS-95, & Microsoft-PWS.
