June 2011 Web Server Survey
In the June 2011 survey we received responses from 346,004,403 sites.
Apache was the only major web server software to gain hostnames this month, with growth of 21M and nearly 2.2 percentage points of market share. The largest growth was seen at OVH, which gained more than 8.6M Apache hostnames. Large growth was also seen at Softlayer (5.6M), AmeriNOC (2.5M) and Hanaro Telecom (1.3M).
Among the other server vendors, Microsoft saw the largest loss with 1.4M fewer hostnames than in May. The majority of this loss was caused by VPLS losing nearly 1.5M hostnames.
nginx lost 1.2M hostnames, spread across a large number of hosting companies. The largest loss was at Ecatel, which saw a drop of nearly 700k hostnames.
Google experienced the smallest loss this month with 262k fewer hostnames than last month.
