In the January 2012 survey we received responses from 582,716,657 sites, a growth of 4.9% or 27.2M sites on last month.

All major web server vendors have continued to gain hostnames this month with Apache, once again, achieving the largest increase of just under 16M hostnames. Despite this, Apache's market share fell by 0.3%, negating the increase experienced last month. Although Microsoft gained 1.8M sites it recorded a further drop in market share, extending a trend that dates back as far as June 2010. Conversely, nginx was the only major web server vendor to gain market share this month and set a new all-time high of 9.63%. Furthermore, it saw the second largest absolute growth with an addition of 6.9M hostnames.

In terms of Active Sites, nginx gained 1.9M which resulted in it overtaking Microsoft to have the second largest number of Active Sites (22.2M). Apache experienced the greatest rise this month with an addition of 3.7M Active Sites, more than double the increase it recorded last month.

Across the million busiest sites, Apache and Microsoft both lost market share this month whilst nginx and Google saw a small increase.
