Around 1:30am CEST one of the job worker instances stopped processing assigned jobs. This could have lead to jobs being stuck in the processing state for a long time without any activity.
At 11:15am CEST the worker instance was terminated and all unfinished jobs started processing on other instances.
We're sorry for this inconvenience.
Database storing locks was restarted at 03:49 UTC which caused the job failures. Also some of the jobs were queued after this failure.
The backlog of all jobs was cleared at 06:15 UTC. The system is fully operational now. We're working on infrastructure changes which should prevent similar issues.
The maintenance period in the US region has just finished. All systems are back online and working properly.

The maintenance period in the EU region has just finished. All systems are back online and working properly.
