  1. Investigating

    ```

    A certificate authority incident has caused Google Trust Services to revoke a number of TLS certificates for astronomer.run, which Astro deployments use for HTTPS access. Users whose browsers or network gateways enforce certificate revocation checks may be unable to access the Airflow UI or other HTTPS endpoints of affected deployments.

    Our engineering team has identified the affected certificates and is replacing them to restore access. We will provide an update as certificates are reissued.

    ```

  2. Monitoring

    We have successfully revoked and reissued all affected certificates revoked by Google Trust Services, and functionality has returned to normal. We are continuing to monitor the situation.

  3. Resolved

    This incident is resolved, and service has returned to normal. All revoked certificates have been renewed, and we’ve confirmed that no additional certificates will be revoked in connection with this incident.
