Xbox Live outages, they've decided to redefine the verbage, newspeak style. Apparently the term "Status: Up and running" has now been expanded to include a laundry list of "intermittent issue" caveats some users might be experiencing, including but not limited to trouble with: "Tournaments, Storage Downloads, Gamer Tile, Statistics through Arbitration, Match Making, and Messaging." If you're hoping to play Halo 3 or Call of Duty 4 online (you rebel, you) you're most likely even more out of luck. There are also far-reaching problems that trace back to Windows Live IDs, so there's a decent chance that your Zune account is on the fritz at the moment as well. But don't worry, it's all up and running.
