In the April 2010 survey we received responses from 205,368,103 sites — a slight fall in the number of sites found.

Three of the five major web servers lost hostnames compared to last month. The two servers to gain sites in the April survey are Microsoft, with over half a million more sites than in March, and nginx with just over 300k new sites. For nginx this reverses the trend of the last three months, when it lost sites due to stale WordPress blogs being expired from the survey.

The survey results this month also show how Chile's internet infrastructure has been affected by the earthquakes which hit the country at the end of February and beginning of March. The two major earthquakes had magnitudes of 8.8 and 6.9 respectively and it is estimated that they took out up to 60% of networks. Despite the scale of the disaster, the number of hostnames seen in Chile this month fell by only 12%.
