  1. investigating Oct 29, 2025, 04:05 PM UTC

    We are currently investigating an apparent issue with Azure's Front Door CDN that is causing DNS timeouts and unavailability of the Astro Cloud UI. Airflow deployments are unaffected and continue to process tasks. We have updated our DNS routing to bypass Front Door for now and are seeing access to the Cloud UI being restored.
