Apple’s system status page is showing that iMessage and four iCloud services – Photostream, Documents in the Cloud, Backup and iPhoto Journals – have been down for some users for more than six hours …
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.
Users may have been unable to create a new Apple ID.
Apple says that fewer than 1 percent of users are affected.
Most Apple outages are relatively brief and affect only a small minority of users, but its Developer Center was offline for a week after a security researcher pointed out a vulnerability that could expose user data. Apple introduced a similar status page for its developer portal during the outage.
Update: After 11 hours and a short period of time where the iTunes Store wasn’t available to some, all services are now back online.
