January 2003 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 2003 survey from 35,424,956 sites. Although this represents another slight decrease from the number of responses received in November, it is still greater than October’s all-time low of 35.1 million sites. It is, however, lower than the nearly 36.7 million responses received in last January’s survey.

As usual, Apache, Microsoft, Zeus, and SunONE (formerly referred to as iPlanet in the survey) remained the key players with shares of 62.23 percent, 27.49 percent, 2.08 percent, and 1.33 percent, respectively. The top vendors once again retained their rankings of the previous month, with only Apache increasing its market share (by a mere 0.21 percent). Microsoft’s, Zeus’ and SunONE’s market shares remained flat.

NT-specific servers accounted for 27.72 percent of servers surveyed, representing yet another decrease from the previous month’s 27.81 percent. Apache-specific servers accounted for 63.68 percent, an increase from December’s 63.51 percent. Macintosh-specific servers again decreased slightly to 0.29 percent.

Of the servers surveyed, 16,182,460, or 45.68 percent, had .com domains.
