Every update Firebase posted, oldest to newest, exactly as it appeared on their official status page.

  1. Investigating

    The engineering team is investigating elevated 501 "unimplemented" errors seen in Hosting's API when managing custom domains. It does not appear at this time that the data plane is effected.

  2. Monitoring

    We believe to have found the root cause and are working to restore this portion of our API. We are more confident now that the data plane is unaffected and that this was limited in scope to the management of Hosting custom domains.

  3. Resolved

    The fix is being rolled out. The ETA for complete resolution is July 31 at ~11:00 UTC, though some users may have restored functionality before then.
