## Timeline of updates

- **investigating** 2026-11-12 14:18 UTC: 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.
