We continue to work on remediating the service disruption in AWS us-east-1. Confirmed impact: - Authentication — a subset of requests may fail - Schema Registry — authorization errors on a subset of requests - ksqlDB — a subset of queries/requests may be affected - Flink — statement management operations (create/update/delete) are degraded, and some running Flink jobs may fail or restart - Kafka operations (create, delete etc) Not impacted: Kafka cluster data-plane operations are not affected by this incident.
