Today around noon we made a lecture template project available to our students and subsequently experienced hours long delays when the docker images for the forked projects were build. Building the images was fine, but uploading didn’t work and led to a timeout after 1hour.
Sample job that timed out is 127367.
Though stopping and restarting jobs might not have been the best idea for you to debug this. I guess it’s possible that again everyone tried to fork our template project at the same time and caused a bit of a hold up. But it did persist roughly between 12:15 and at least 14:30 or so.
