Exactly like @backdraft says. My site, as well as many other ones I've been monitoring have experienced just what you are experiencing today - this was 2-3 days ago. They have returned to normal TODAY, which is kind of the opposite of what has happened in your case.
EDIT: Backdraft, you can check out my message on the previous page (msg:4594610) for more.
