March 2012 Web Server Survey

In the March 2012 survey we received responses from 644,275,754 sites, giving a rise of 31.4M hostnames (5.1%) since last month.

Apache continued to gain hostnames this month with a growth of 22.5M and, contrary to last month, was able to increase its market share by a third of a percentage point. nginx had another good month and experienced an increase of 4.7M hostnames or 7.82%. With all other major web server vendors showing higher growth than Microsoft's 761k increase, Microsoft recorded a drop in market share of half a percentage point. The gap between Microsoft and nginx now stands at 23.6M hostnames.

Amongst the Million Busiest Sites, Apache again suffered a small drop in market share this month, losing 1,700 sites, extending a trend that dates back to August 2011. Microsoft gained 110 sites making this the first time it has recorded an increase since June 2010. nginx continued to increase its market share and gained 1.2k sites, whilst Google suffered a small loss of 289 sites.
