December 2010 Web Server Survey

In the December 2010 survey we received responses from 255,287,546 sites.

This month's largest change in market share was seen by nginx, which gained 0.59 percentage points and now serves 6.62 percent of the hostnames in the web server survey. The increase of 1.85M hostnames is mainly due to 656k Savvis hostnames moving from lighttpd to nginx, and 452k new hostnames on BurstNet.

The biggest losses in market share this month were seen by Microsoft, which lost 0.48 percentage points (but gained 85,564 hostnames), and lighttpd, which lost 0.32 percentage points. Many of the 761K hostnames lost by lighttpd can be explained by the large number of Savvis hostnames moving to nginx. The other major web server vendors all gained hostnames whilst losing small amounts of market share.

Open source HTTP accelerator Varnish gained 545k hostnames. A recent blog post on the varnish site identifies WikiLeaks as one particularly prominent user of the software, with both cablegate.wikileaks.org (performance graph) and warlogs.wikileaks.org (performance graph) served by Apache via Varnish.

Other highly popular sites such as Facebook, Twitter and eBay are also on record as being users of Varnish, although this is not evident from their server banners.
