We’ve noticed a significant number of 401 responses over the past 24 hours while performing OAuth API requests. We believe the credentials and request construction to be valid, as retrying the request after some period of time tends to succeed. This code is relatively stable and hasn’t changed in a very long time.
There were at least two windows where this occurred, one starting at 2012-01-05 01:05:35 UTC and another at 2012-01-06 00:35:42 UTC. We suspend credentials on 401 so we don’t have information about how long the API was in this state.
Is anyone else experiencing this? Perhaps a known issue?
