Users Experiencing Extended iMessage, iCloud Service Outages [Update: Restored]
Multiple Services - Less than 1% of users are affectedApple's verious cloud services have experienced occasional downtime, although outages extending for this length of time are fairly unusual. This extended outage does, however, only appear to be affecting a relatively small number of users.
Users may be unable to use iCloud Documents, Photo Stream, iPhoto Journals, or Backup & Restore. Users may also be unable to send or download attachments in iMessage.

Update 9:09AM PDT: Apple claims all services have been restored.
