RSSThe Security Space Web Server Survey is a survey of Web server software usage on the Internet broken down by 86 domains. Security Space estimates that even though there are almost 20 million Web sites, nearly 90 percent are "orphans" to which no other sites link. Security Space's Web server survey counts only those servers referenced on other sites.
Nearly 12 million Web sites responded to the September 2003 survey, exceeding August's peak of 11.5 million sites. Nearly 6 million of those, or 50.04 percent, had .com domains.
