We are currently observing elevated task failures and latency for some deployments running in the AWS us-east-1 region. This is related to an ongoing AWS incident affecting a single Availability Zone (use1-az4), where EC2 and EBS resources have experienced impairments. What to expect: You may see intermittent task failures or retries in your deployments. In most cases, these failures are transient and should self-resolve automatically as AWS continues recovery. What you should do: No immediate action is required. However, if you notice consistent or prolonged failures, please reach out to Astronomer Support, and we’ll help investigate further. We are continuing to monitor the situation closely and will share updates as needed. Refer: https://health.aws.amazon.com/health/status

We are continuing to monitor the situation as AWS works toward full recovery in the affected Availability Zone. At this time, we are seeing signs of stabilization, and most transient failures should continue to self-resolve. We will provide further updates once AWS confirms that the issue has been fully resolved.
- resolved May 09, 2026, 01:43 AM UTC
AWS has confirmed recovery in the affected Availability Zone (use1-az4), and system performance has returned to normal levels. We are no longer observing elevated task failures or latency in the AWS us-east-1 region. Any previously impacted workloads should now be operating as expected. If you continue to experience issues, please reach out to Astronomer Support for assistance.
