Has hell frozen over? Or is Windows Server more reliable than Linux?

For the last week, according to Netcraft, Windows is #2 behind FreeBSD for web servers and it outnumbers all other OS’s in the top 50. Linux isn’t even on the list?

See the list for yourself. The list is limited for the most requested sites due to notability and performance reasons.

Either MS has done a bangup job convincing sys-admins to keep their servers up to date and secure, or Linux is starting to slip a little. This is the first time I’ve seen BSD being threatened in the weekly averages and Linux completely falling of the list.

FreeBSD in particular is one of the most stable (arguably the most stable) platform for servers so no surprise there. But Windows Server?!
