Since Friday, CI was unable to process changes receiving a CR+2 if they
declared a Depends-On on an opened change. The issue should be fixed as
of 21:30 UTC when I hotfixed Zuul.
I would like to thanks:
* Kunal Mehta to have taken on his personal time to restart Zuul over
the week-end and restore the service multiple time.
* Paladox also assisted in pointing out the root cause.
* Tyler Cipriani who live peer reviewed the debug session
My apologizes to all patches and developers that got affected.
I will write an incident report later on and reply on this thread when
it is complete.
