MicroSoft amplification?

So with all the noise about Code Red, and in the process of trying to
recover from various attacks, I happened to try to ping
www.microsoft.com.  It's probably par for the course that this happens:

I find it interesting and almost amusing that MicroSoft's own web server
can be used for amplification attacks.
