Microsoft has temporarily closed Xbox Live, Xbox.com and its forums for a day of maintenance.

From 10am today (UK time) until midnight tonight all of the servers across the globe will be shut for a major overhaul. During this downtime, Bill's boys in white coats are expected to upgrade the service to give Xbox 360 owners the ability to download video and clips direct from E3.

Which means until 00:01 on Wednesday morning when the servers are turned back on, you'll have to go cold turkey on Geometry Wars. Don't worry, you'll make it.
