Transit Gateway Connections UI Shows Failed State

Incident Report for Confluent Cloud

Resolved

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).
