Since 2003, Port80 Software has periodically surveyed the public sites of Fortune 1000 companies to determine their use of Web and application hosting technologies. In a survey released today, the Microsoft Internet Information Services 6.0 Web server (IIS 6) gained 9.5% since August 2006 and passed IIS 5 to lead the survey for the first time, outserving the open source Apache server and all other Web servers among Fortune 1000 sites. Overall, IIS 4, 5, 6, and 7 deployments continue a four year lead in the survey with a combined 55.0% share of all Fortune 1000 corporate sites versus Apache’s 24.9% share.
