Why is my iPhone 5 imessage not working all of a sudden?

This has never happened before. It was working fine all day up until about an hour or so ago. I tried restarting and all of the "fixes" but nothing worked… Help!

There's currently a problem with Apple's iMessage servers, this affects some people, but not everybody.

This page will tell you when it's working again: http://www.apple.com/...temstatus/
