World's Largest TFS Deployment?

I have not heard of any customer going bigger than this:

November 2008	Growth	Totals
Unique Active Users	+170	15,308
Total Active Users	+377	17,388
Projects	+125	2,749
Work Items	+167,598	3,050,512
Source Code Files	+2,441,418	47,418,877
Total Builds	+60,121	584,380

Microsoft just passed the 3,000,000 Work Items mark! And fast approaching the 50million source code file count. All that across 27 instances, three of which are Rosario builds and 24 on TFS 2008 SP1.

Thanks to Joe Schwetz for sharing these internal use numbers - makes me proud that we have such confidence in our own products that we not only dogfood them, but also support our core business of software development using Team Foundation Server.
