January 2006 Netcraft Survey Highlights

The Netcraft Web Server Survey is a survey of Web server software usage on the Internet. Netcraft received responses to its January 2006 survey from 74,951,256 sites. This is about 1.9 million fewer sites than responded in October.

The response was slightly higher than the December dip of 74,353,258 sites, which was a decline of nearly 2.2 million sites from November and the first decline since January 2003. Despite these losses, it was a record year for Internet growth, with 17.5 million sites being added in the first 10 months of 2005.

Not surprisingly, three of the top-four players experienced declines during this period: Apache declined 6.5 percent; Microsoft (which includes Microsoft-Internet-Information-Server, Microsoft-IIS, Microsoft-IIS-W, Microsoft-PWS-95, and Microsoft-PWS) declined 2.6 percent; and Zeus declined 9.3 percent.

Sun (which includes SunONE, iPlanet-Enterprise, Netscape-Enterprise, Netscape-FastTrack, Netscape-Commerce, Netscape-Communications, Netsite-Commerce, and Netsite-Communications), however, saw the number of sites powered by its servers increase 4.85 percent.

Collectively, these four players now account for 90.49 percent of all sites counted.

Of the sites surveyed, 39,705,278, or 52.97 percent, had .com domains; 4,210,070, or about 5.62 percent, had .uk domains.
