Increased authentication failures

I’m seeing a spike in authentication failures these recent 2 weeks. I heard something was changed recently in regards to authentication. Maybe a new bug was introduced?

This graph shows where the user, through the code flow, did not get a token or the root resource did not properly return the given username when the token was attached:

We’ve been pushing out changes to auth over the past few weeks, transitioning oauth token handling from an old service to a new service. Many bugs seem to have come up as a part of this, and we’re addressing them as they are found.

It looks like one of those spikes was indeed a bug that was handled recently, and there is a known bug from today that might cause a spike.
