It's not unusual these days for some popular Internet service to experience an outage. Many of the big ones last a few hours at most. The most recent that drove the Internet nuts was YouTube, which went back up in around an hour. Unless your livelihood depends on YouTube, however, that may have not had much practical impact. When some of Apple's iCloud services like Documents, Backup, and even Sign-in go down for almost half a day, however, you can be forgiven if you find it odd there wasn't much uproar over it.
