October 2011 Web Server Survey

In the October 2011 survey we received responses from 504,082,040 sites, a growth of nearly 3.8% or around 18M sites on last month.

All of the main web server vendors gained hostnames this month with Apache again showing the largest increase of just over 10M; however, it continues to lose a small amount of market share. A gain of just over 4M hostnames sees nginx increase market share to an all-time high of 8.5%.

This month Apache lost 86k active sites, less than 0.1% of its total. However, this translates to a more significant loss in market share of 1.09% due to all three of the main competitors gaining sites. The largest gain was seen by nginx, where an increase of just over 1.6M active sites resulted in its market share rising to 11.28%. If current trends continue nginx will soon overtake Microsoft to have the second largest number of active sites.

Across the million busiest sites Apache and Microsoft each lose market share this month whilst nginx and Google see small increases.
