  1. investigating Oct 31, 2025, 09:12 PM UTC

    [Firebase Data Connect] Customers in europe-west1 may see elevated error rates and latency since around 1:10am Pacific Time on October 31st, 2025. This affects control plane actions such as creating, updating and viewing resources (such as services and schemas). Data plane operations like serving end user requests are not affected. We're still investigating the issue.

  2. resolved Nov 01, 2025, 12:52 AM UTC

    The issue has been mitigated on our end. Customers should now be able to change resources (e.g. firebase deploy) normally. For customers who ran into partial / total failures during an earlier deployment, we recommend double-checking the current resource status and deploying again if needed.

  3. resolved Nov 01, 2025, 02:21 AM UTC

    (The service has been in a stable state since last update. We just want to give an update to the cause.) The issue was due to a bad rollout in a downstream dependency, and our engineers have mitigated the issue by fully rolling back to a previous version. We are continuing to monitor the situation to ensure the issue is fully resolved.
