It is interesting to compare the latest Netcraft web servers survey to the January ones.

In terms of active sites , Apache has now 67.54% market share (66.42% in January), and IIS has 23.98% (vs 24.79%).
Open source is going well in some areas!

Another interesting point of this survey is that Network Solutions is moving back a quarter of a million sites to Solaris after they moved them to IIS one year ago. Hum... I wonder why they come back ;-)
