We're well aware the first three words on the Xbox Live service status box are "up and running," but those issues are continuing to persist, and if our flooded tip jar and the Xbox Live forums are anything to go by, they're probably not just "intermittent". If you're (still) seeing issues, as always feel free to shout it out, as well as hit our poll so we can keep track of just how severe this stuff is. (So far, of those polled who've been trying to use Live, roughly 75% responded that they've been experiencing moderate to severe issues.)
[Thanks to everyone who sent this in]
Update: Status now reads "up and running," zero caveats. Let's hope that's the way things stay! Thanks, xboxman.
