Started Oct 22, 2026, 12:01 AM UTC· resolved Oct 23, 2026, 09:28 PM UTC

  1. identified Oct 22, 2026, 12:01 AM UTC

    Astronomer has released Runtime updates to address a publicly disclosed security vulnerability concerning private keys associated with eight eMudhra/emSign intermediate certificate authority (CA) certificates. For additional background, visit https://emudhra.we-have-a-problem.com/. Scope and available updates This advisory stems from an issue with a third-party certificate authority. Action required for customer-managed components depends on their specific certificate trust stores and verification mechanisms. The following Runtime releases incorporate certificate trust updates to mitigate this vulnerability: • Runtime 13: 13.12.1 • Runtime 3.0: 3.0-20 • Runtime 3.1: 3.1-23 • Runtime 3.2: 3.2-12 • Runtime 3.3: 3.3-10 For full details, please refer to the Runtime release feed: https://www.astronomer.io/docs/runtime/runtime-release-feed. Recommended customer actions • Upgrade to the appropriate updated Runtime release for your environment. • Rebuild and redeploy custom images using the updated base image. Refer to our mitigation guide: https://www.astronomer.io/docs/runtime/mitigate-emudhra-ca-compromise for step-by-step instructions. • Audit customer-managed build pipelines and tooling, applying relevant vendor updates to certificate trust stores and signature verification components. • Ensure TLS and code-signature verification remain enabled. If updates cause validation failures, contact the endpoint owner or software publisher for replacement certificate or artifact guidance. Please note that Runtime updates address the trust components included within those specific releases. Customer-added dependencies, custom certificate bundles, and external tooling may require separate updates. Support and further guidance If you are unable to upgrade or require assistance determining the applicable next steps, please contact [email protected]: mailto:[email protected]. Include your deployment model, Runtime version, and whether you maintain custom images or build pipelines. Additional mitigation guidance is currently being finalized. We will update this advisory as further details and Remote Execution releases are confirmed.

Minor October 6, 2026 Capacity constraints in GCP us-central1 may delay or fail some task executions 7d 21h Astro Hosted (Scheduling and Running DAGs and Tasks), Astro Hybrid (Scheduling and Running DAGs and Tasks)

Started Oct 06, 2026, 03:33 AM UTC· resolved Oct 14, 2026, 12:34 AM UTC

  1. investigating Oct 06, 2026, 03:33 AM UTC

    We are currently seeing a capacity shortage in the Google Cloud (GCP) us-central1 region. As a result, some Deployments running in this region may experience delays when scaling up worker nodes and pods. Some tasks may remain in a queued state for longer than usual while waiting for compute capacity. In some cases, tasks that stay queued beyond their configured timeout may fail. Recommended workaround: Configuring automated task retries (for example, setting retries and a retry_delay on your tasks or in your DAG's default_args) will help tasks recover automatically once capacity becomes available. https://www.astronomer.io/docs/learn/rerunning-dags#automatically-retry-tasks We are working to address the issue and keep this page posted as we have more updates.

  2. resolved Oct 14, 2026, 12:34 AM UTC

    We have seen improved capacity in the GCP us-central1 region across additional machine types, and error rates for worker node and pod scale-up have dropped. If any tasks failed during this incident, you can clear and rerun them. To recover automatically from future capacity constraints, we recommend setting retries and retry_delay on your tasks or in default_args. If you’re still seeing issues, please contact Astronomer Support.

Major September 17, 2026 Permissions silently dropped from custom roles 1h 35m Astro Hosted (Deployment Access), Astro Hosted (Deployment Management), Astro Hosted (Cloud API), Astro Hybrid (Deployment Access) and 2 more

Started Sep 17, 2026, 05:54 PM UTC· resolved Sep 17, 2026, 07:29 PM UTC

  1. identified Sep 17, 2026, 05:54 PM UTC

    We have identified a regression affecting custom roles due to a change rolled out today. This resulted in permissions being dropped from custom roles silently. We have received reports of deploys linked to tokens using custom roles not working. Until the fix has been rolled out, deploy failures can be mitigated by re-adding the deployment.deploys.create permission to your custom role. You may also manually restore any other permissions that were silently dropped. We are working on fixing this regression for all affected custom roles.

  2. monitoring Sep 17, 2026, 07:29 PM UTC

    All custom roles have been restored to their previous functionality and full operation has been restored.

  3. resolved Sep 17, 2026, 09:50 PM UTC

Major September 8, 2026 Tasks remain in the queued state on some worker queues. 7h 35m Astro Hosted (Scheduling and Running DAGs and Tasks), Astro Hybrid (Scheduling and Running DAGs and Tasks)

Started Sep 08, 2026, 12:33 PM UTC· resolved Sep 08, 2026, 08:09 PM UTC

  1. identified Sep 08, 2026, 12:33 PM UTC

    We have identified the cause. On Astro, each worker queue is backed by a Kubernetes autoscaling resource whose name is built from a fixed platform prefix, the deployment release name, and the worker queue name. For a very small number of customers, where that combined name exceeds the Kubernetes 63-character limit, the autoscaling resource is rejected at creation. As a result, workers do not scale for the affected queue and tasks routed there remain in the queued state. This is why the limit can be reached even when the worker queue name itself looks short: the release name and platform prefix already consume a large portion of the 63 characters before the queue name is appended. Workaround: If affected, until the permanent fix is deployed, please keep worker queue name at or below 10 characters. We are preparing a permanent fix. Further updates to follow.

  2. monitoring Sep 08, 2026, 07:42 PM UTC

    A fix has been implemented, and we are monitoring the results.

  3. resolved Sep 08, 2026, 08:09 PM UTC

    The incident has been resolved.

  3. identified Sep 04, 2026, 04:52 AM UTC

    The potential root cause identified, and fix is underway

  4. monitoring Sep 04, 2026, 05:53 AM UTC

    We identified and resolved an infrastructure configuration issue that was causing authentication failures and deployment access errors across the platform. The root cause was a network configuration change during an infrastructure upgrade that temporarily disrupted connectivity between our control plane and customer deployments. The fix has been applied and initial validation confirms services are recovering We are actively monitoring to confirm full recovery across all affected deployments. If you are still experiencing issues, please contact support.

  5. resolved Sep 04, 2026, 06:07 AM UTC

Minor May 8, 2026 Increased Task Failures in US-East-1 (AWS) - AWS Incident 18h Scheduling and Running DAGs and Tasks, Scheduling and Running DAGs and Tasks

Started May 08, 2026, 07:43 AM UTC· resolved May 09, 2026, 01:43 AM UTC

  1. investigating May 08, 2026, 07:43 AM UTC

    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

  2. monitoring May 08, 2026, 07:45 AM UTC

    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.

  3. 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.

Started May 07, 2026, 10:31 AM UTC· resolved May 07, 2026, 02:24 PM UTC

  1. investigating May 07, 2026, 10:31 AM UTC

    We are investigating delayed delivery for some time-based alerts. The delay is primarily visible for DAG Timeliness alerts, and may also affect Observe-related SLA, Proactive SLA, and Data Quality monitor alerts. DAG Duration and Task Duration alerts do not appear to be affected at this time.

  2. identified May 07, 2026, 11:15 AM UTC

    We have identified the cause of the delayed delivery for some time-based alerts and are implementing a fix. We will provide another update once the fix has been deployed and validated.

  3. identified May 07, 2026, 12:57 PM UTC

    A fix has been prepared and is moving through deployment. We will provide another update once the rollout is complete and validation is underway.
