  1. Investigating

    We are investigating data plane impact (produce/consume) resulting from elevated error rates and latencies from AWS us-east-1 resources in AZ4. EC2 instances hosted on this availability zone are impaired by loss of power during an ongoing thermal event.

  2. Monitoring

    We are monitoring the health of impacted brokers in the affected availability zone. More details about the thermal event on the AWS status page: https://health.aws.amazon.com/health/status

  3. Monitoring

    AWS has resolved the underlying infrastructure issue in us-east-1 (use1-az4). The majority of Confluent Cloud services have recovered and are operating normally. We are continuing to monitor for any lingering effects and verifying full service restoration.

However, some Confluent Cloud customers in the affected availability zone continue to experience connectivity issues. Confluent is actively investigating and working to restore full connectivity for impacted customers.
