Downdetector had 5,755 reports of AWS problems at 12:52 AM Pacific (3:53 AM Eastern).

That number had dropped to 1,190 by 4:22 AM Pacific (7:22 AM Eastern).

However, that number is back up with a vengeance. 9,230 reports as of 9:32 AM Pacific (12:32 Eastern).

Part of that could be explained by more people making reports as the U.S. west coast awoke. But I also have a feeling that they aren't yet on top of the problem.
