This incident has been resolved. We have observed that instance rates are returning to normal levels and affected connectors are syncing successfully. Incident Summary Description: We identified an issue on the Fivetran Connection Status page that caused Sync Events not to display correctly in the event log. Timeline: This issue began on March 12th at 18:14:00 UTC and was resolved on March 12th at 21:30:00 UTC. Cause: The issue was caused by a recent code change that allowed malformed messages to be accepted by our backend service. These malformed messages could not be processed, resulting in a backlog of properly formatted messages. Resolution: We deployed a hotfix to handle the malformed messages. Once those malformed messages were handled properly, the backlog of correctly formed messages began to be processed, and UI events recovered.
