No, it’s not your imagination. Some of Apple’s online services have been down this morning. A quick look at the Apple System Status page shows that the iTunes Store was down for 16.6 percent of all users between 8:57 and 9:42 AM ET, and that continuing outages affecting less than 1 percent of all users are making life difficult: “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.”
If you’re one of the affected users, be sure to keep a close eye on the status page to see when services reappear for you.
