May 2007 Web Server Survey

In the May 2007 survey we received responses from 118,023,363 sites, an increase of nearly 4.4 million sites from last month. The Internet has added 12.8 million web sites thus far in 2007, roughly on pace with growth in 2006, when the Web gained a record 30.9 million sites.

With this month's survey, Netcraft has begun tracking Google's custom web server software known as GFE (Google Front End), which is currently found on 2.7 million hostnames, or 2.3% of all sites. Google customizes its web infrastructure, with in-house solutions for software and hardware, including energy-efficient servers and power supplies. GFE is the server found on Blogger sites at blogspot.com, while Google uses GWS (Google Web Server) on some other services, although none with the volume of hostnames seen at Blogger.

The GFE hostnames had previously been grouped under Apache, which sees a reduction in sites. As a result, Apache's market share slips by 2.86 percent to 56 percent, while Windows has a modest gain of 0.36% to 31.5 percent.
