A 'warez' group named iNFLUNCE (or possibly iNFLUENCE) claimed responsibilty, our source says.
The beta site contains test versions of Microsoft software including forthcoming Windows test code. The company says the hackers weren't able to land any source code, but were able to scarper with some "buggy" software.
Here's a Microsoft missive delivered to its testers:

A red-faced Vole later posted this missive on a Microsoft Newsgroup:
Beta Testers,
We continue to experience system problems with both the Windows Beta and BetaPlace sites, and they remain down for maintenance. Thanks for your patience.
Microsoft Beta Services and the Windows Beta Teams
The poor dears. ยต
