It looks like the team that runs all of the Microsoft.com sites have started a blog (http://blogs.technet.com/mscom/default.aspx).  Their first post has some great information on the number of servers they are running, the number of hits on www.microsoft.com, and all kinds of other interesting stuff.

More importantly, as their post states: WE WANT TO HELP YOU!

So if you have operational questions, head over to http://blogs.technet.com/mscom/default.aspx and see if they have an answer for you.
