July 2011 Web Server Survey
8th July, 2011
In the July 2011 survey we received responses from 357,292,065 sites.
Apache gained a further 10.8 million sites this month, taking its total up to 235 million and increasing its leading market share by nearly a whole percentage point to 65.9%. OVH, who saw massive growth of 8.7M hostnames last month, gained a much smaller but still significant 1.5M this month. The largest growth was exhibited by Softlayer, gaining 3.5M.
Microsoft IIS is now used by more than 60 million websites, a growth of 1.9M hostnames, capturing 16.8% of the market. Though most of these sites are served directly from Windows computers, fronting Windows machines with an F5 BIG-IP load balancing device remains a popular option and is used on around 8% of Microsoft IIS sites. Microsoft themselves serve nearly half a million hostnames on IIS through BIG-IP, for example http://windows.microsoft.com. VPLS, Inc., who saw a big drop of 1.5M last month, saw the biggest growth this month, adding 800k hostnames and more than doubling their total.
Despite gaining 689k sites, nginx's share fell slightly this month to 6.54%. Google suffered a slight loss last month, and also experienced the largest loss this month, with its total falling by a further 317k sites.
