March 2007 Web Server Survey

In the March 2007 survey we received responses from 110,460,149 sites, an increase of 1.64 million from last month. The Web crosses the 110 million mark just five months after reaching 100 million web sites in the November 2006 survey, continuing the strong growth trend seen in the last two years.

In the web server market, Apache gains ground in our tracking of active sites, as two large domain registrars see reductions sites on in Windows this month. Microsoft has an overall decline of 242K active sites this month, as it loses active sites at Go Daddy and Demand Media (owner of eNom and BulkRegister). Those setbacks were partially offset by gains at other hosting providers, but Windows loses 0.47% share while Apache gains 0.24%. Web server market share in hostnames, our broadest metric, remains little changed.
