The Netcraft Web Server Survey is a
survey of Web server software usage on the Internet. Netcraft received responses to its
August 2003 survey from 42,807,275 sites. This is 508,904 (1.2 percent) more sites than responded in July, and it represents a new peak in the number of responses received.
As usual, Apache, Microsoft, and Zeus were among the top-five Web server, with shares of 63.98 percent, 23.75 percent, and 1.81 percent, respectively. This month, Sun Microsystems joined them, with Netscape Enterprise dislodging Zeus Web Server from third place and into fifth. This redistribution is due to Sun increasing its share by nearly 2 percent in the past month and Zeus’ share declining marginally. Microsoft also continued to lose sites, this time 2.2 percent — 810,597 sites. Netcraft attributes the decrease to Network Solutions migrating the remainder of its domain parking system back to Solaris from a Windows-based system hosted at Interland.
Of the servers surveyed, 20,374,593, or 47.6 percent, had .com domains; 2,843,887, or about 6.6 percent, had .uk domains
