August 2003 Web Server Survey

The Netcraft Webserver Survey is 8 years old this month. Happy Birthday!

The first Web Server Survey ran in August 1995 and found 18,957 sites. NCSA and CERN were the leading web servers of the day, in front of Netscape which had recently IPO'd, and the Apache project which started a few months earlier in March 1995. Microsoft-IIS, HTTP/1.1 hosting and domain name registrars were not then on the horizon.

In the August 2003 survey we received responses from 42,807,275 sites.

Apache hits an all time high in percentage share this month with 63.98% of sites found running an Apache server.

Following on from last month, Microsoft continued to lose sites as Network Solutions migrated the rest of their domain parking system back to Solaris from a Windows based system hosted at Interland. This is primarily responsible for Microsoft's 2.2% fall, with a net loss of 810,597 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.
