So I guess it is only maintenance and nothing more.

Microsoft send word that tomorrow, April 1, will see Xbox Live down for maintenance between the hours of 0200-0500 Pacific Time. Anyone hoping for some kind of April Fool's Day surprise like an XBL update from Microsoft should do less hoping and more facing reality, as the downtime's for server maintenance, which means "there are no new features...that will appear on your Xbox 360 console or Xbox.com when the service comes back online".
Reminder: Xbox Live Maintenance on Tuesday April 1 [Microsoft]
