Incident Report for Fivetran

Resolved

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.

Monitoring

We have deployed a fix for this issue: We created a hotfix to handle malformed messages which were preventing normal messages from processing

We will continue to monitor all affected sync events until we are caught up and the Connection Status page is back to normal.
