In 8/03, Microsoft changed its DNS so www.microsoft.com would not be handled by Microsoft's in-house servers, but by the Akamai caching system, which runs Linux.
But the plot thickens... how can they be using Linux and IIS 6.0?
Check this out:
Code:
$ telnet www.microsoft.com http
Trying 213.161.82.44...

It's a mystery...
