The 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 includes only those servers referenced on other sites.
More than 8.4 million Web sites responded to the November 2002 survey, down for the second consecutive month from the more than 9 million responses received in October. More than 4.4 million of those, or 52.93 percent, had .com domains.
