New Survey: Microsoft IIS Serves More High Traffic Web Sites Than Any Other Web Server, Including Apache

Microsoft IIS Web servers deliver over 40% of the 1000 highest traffic sites on the Internet, contrary to popular belief. Port80 Software's new survey provides a counterbalance for business decision makers to the popular Netcraft Web Server Survey (which tracks the open source Apache Web server as the world's most deployed Web server).

San Diego, CA (PRWEB) February 6, 2004 --A new survey conducted by Port80 Software of the 1000 most-visited Web sites on the Internet reports that Microsoft Internet Information Services (IIS) serves more high traffic sites than any other Web server, including open source Apache. Based on the best available data from Nielsen//NetRatings, the global standard for Internet audience measurement, Port80 Software analyzed the top 1000 highest traffic sites to determine which Web server software they are using.

Port80s Top 1000 Corporations' Web Servers Survey, analyzing US Fortune 1000 Web sites, has been intensely debated since its inception in January 2003. The company challenges the relevance of the popular Netcraft Web Server Survey for business decision makers, asserting that the Port80 surveys better reflect the large enterprise Web server market. This new Top 1000 High Traffic Web Servers Survey was conducted to illuminate market share among those sites that demand the most out of their Web server software: the most visited destinations on the Internet.

Netcraft canvases millions of sites, whereas Port80 focuses on selective samples of high traffic and major corporate Web sites," said Joseph Lima, COO of Port80 Software. In response to our Fortune 1000 survey, many critics suggested that sampling the highest traffic sites would make for a more enlightening survey. Each survey provides a different picture of the Web server market and, while there is no definitive answer, we hope that this high traffic survey adds a significant new perspective to the debate."

Port80 Software's January 2004 survey of the Web server software used by the 1000 highest traffic Web sites revealed the following market shares:

Microsoft IIS:     43.1%
Apache:             39.7%    
Netscape Enterprise: 8.7%
Other Web servers: 8.5%
