Many iCloud Services are out
Apple’s System Status page is showing that there are currently five services that are not working for some users. The services that are down are iPhoto Journals, Photo Stream, Documents in the Cloud, Backup, and iMessage. According to Apple, the services have been out for almost 12 hours now.
Multiple Services - Less than 1% of users are affected
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.
This is the most services that have ever been down at one time. Apple should have this fixed later today. To stay on top of what is up you can refer to this page.
