P.S. -Microsoft, congrats on the great holiday season. You obviously sold a TON of Xbox 360s and Live service contracts. Now be a doll.

Update: Our broham Major Nelson says the Live engineers have identified a fix for the issues and things are on their way to being back on the up and up. Hopefully this time for good!
