    Service Disruption affecting Authentication, Schema Registry, ksqlDB, and Flink in AWS us-east-1

    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. This issue is isolated to the AWS us-east-1 region; other regions are unaffected

What to do next

  • Verify your own services recovered cleanly. Some upstream outages leave queues or caches in a degraded state, run smoke tests before declaring green internally.
  • Save the post-mortem. Vendors usually publish a detailed RCA 1-3 days later. We'll add it to this page when it appears.
  • Watch the provider going forward. Follow Confluent Cloud's status feed →

GlobalOutageMap aggregates publicly reported signals. We never claim authoritative status, always cross-check the provider's official channel before making business decisions.
