The rollback was completed at about 3:30pm PDT.

You may need to pause and unpause your connector to have the sync succeed. We will monitor and look into connectors still receiving this error at the end of today.

Identified

We've identified a recent change to the disconnect behavior which is causing reconnects to binlogs to throw the following error a subset of MySQL connector users:

"ServerException: A slave with the same server_uuid/server_id as this slave has connected to the master;"

Fivetran engineering is rolling back the change now. We're currently targeting 3pm PDT to complete the rollback.
