As of September 25, 2025, customers may observe that their AWS Transit Gateway connection is in a Failed state from within the Confluent Cloud UI. However this shouldn't impact any of your services or connectivity. From our assessment this is likely a problem from AWS and we have escalated to AWS for resolution.

AWS has confirmed that when an external principal is removed from a customer's resource share, Confluent cannot determine if the TGW attachment still exists. This results in the AWS Transit Gateway connection displaying in the Failed state from within the Confluent Cloud UI. Affected users should validate the TGW resource share is in place per our documentation (https://docs.confluent.io/cloud/current/networking/aws-transit-gateway.html#add-an-aws-transit-gateway-attachment-in-ccloud).
