Just a friendly reminder...if you had planned to play some Co-Op Halo 3 with your brother in Kalamazoo today you may be out of luck. The service is going to be down for up to 24 hours while they implement some pre-update updates for the upcoming New Xbox Experience update. Phew...that's a mouth full.
While you are waiting you can check out the recently launched New Xbox Experience site that lets you test drive the new Xbox Dashboard.
We'll update this post when Xbox Live is back online, though it could be after midnight Eastern today. For now...Billy is sad.
Update: Finally as of 5AM Eastern this morning XBox Live is back online.
