In the August 2008 survey we received responses from 176,748,506 sites. This month's overall growth of 1.3 million sites reflects Apache's growth of 1.2 million and Google's gain of half a million sites, but a loss of 760 thousand sites using Microsoft IIS.
Aside from Apache's and Google's leading growth, Igor Sysoev's nginx shows the next largest gain, climbing by 170 thousand sites to a new total of 2.4 million and retaining its position as the 5th largest web server vendor.
LiteSpeed also shows strong growth this month, more than tripling the number of sites that run on this web server. Most of this growth is seen at the German company Hetzner Online, which remains the largest host of LiteSpeed sites. LiteSpeed is now used by 160 thousand sites around the world, which has taken it up to be the 16th most popular web server.
