One of our core databases in US region has been restarted due to some failures by AWS. All running jobs failed or will fail due to this reason.
UPDATE: The problem affected ca 26 jobs. There was some unspecified low-level failure on the database or its underlying hardware and AWS automatically switched to a backup instance. We are going to investigate if our platform can handle the failure and restart the jobs automatically next time. Thanks for your understanding, we are sorry for any inconvenience.
