We are currently seeing elevated error rates on the old Cellar cluster. A few nodes went down making operations longer than usual, leading to timeouts or 500 / 503 errors. Nodes are already getting back up.
EDIT 00:21 UTC: The cluster is getting back to normal, errors have already significantly decreased and most of the requests should now be successful. We keep monitoring failed requests.
EDIT 03:00 UTC: No more failed request over the last 30 minutes, the incident is closed. We are still in the process of migrating this cluster data to the new cluster. Until we automatically migrate your buckets, you can migrate them yourself. Feel free to contact our support for more information
