September 2010 Web Server Survey

In the September 2010 survey we received responses from 227,225,642 sites.

This month saw the number of responses to our survey increase by nearly 14M sites and a change in web server market share similar to last month's, with Apache continuing to gain at Microsoft and Google's expense. Notable increases include a 1.5M gain in hostnames for Servage, an almost 700% increase over last month, and gains of around 500k hostnames at, SAVVIS and GoDaddy.

Apache experienced a smaller jump in market share this month compared with last despite gaining more hostnames, with an increase of just over 10M. This growth was fairly widely spread across a variety of hosters and it boosted Apache's market share by another percentage point.

Microsoft gained over a million hostnames but it was not enough to prevent a loss of nearly 1 percentage point of market share.

lighttpd's large gains in August were not repeated this month and instead saw a slight drop in hostnames and market share.

nginx also gained 1M hostnames, but with little effect on its market share. nginx continues its slow but steady rise in market share amongst the Million busiest sites. Over the last two years nginx has risen from just under 20k sites to nearly 55k, while Microsoft has lost the same number of sites.
