November 2003 Web Server Survey

In the November 2003 survey we received responses from 44,946,965 sites.

Apache has a significant percentage gain this month as register.com, a leading domain registrar with a domain parking system serving responses for over one million domains eliminated its Windows front end, and reverted to Linux and Apache which it ran previously. Barely weeks ago its largest rival, Network Solutions made a similar switch from Microsoft-IIS back to SunOne, nee Netscape-Enterprise, for its own domain parking system.

During 2001 and the first half of 2002 several companies hosting very large numbers of hostnames including Webjump, Namezero, Homestead, register.com and Network Solutions migrated to Microsoft-IIS. Subsequently these businesses have either failed, significantly changed their business model, or reverted to their previous platform, and Microsoft-IIS share is now in line with its long term pre-summer 2001 level of around 20%.

Wildcard TLDs and the Web Server Survey

Since Verisign wildcarded the .com and .net Top Level Domains [TLDs], some people have become concerned that this might pollute the results of the Web Server Survey, eventually reaching the situation when 99.9% of the hostnames found are running Linux and Apache - Verisign's platform of choice for the site to which they redirect otherwise unresolved requests.

However, Verisign was not the first TLD operator to think of wildcarding their domains, and we already maintain a mechanism for preventing hostnames that resolve to the ip addresses of these wildcarding systems from being included in the survey. Continue reading
