Latest update from Firebase (Firestore & Realtime Database)

The issue with Firebase Realtime Database has been resolved for all affected projects as of Monday, 2025-11-03 18:13 PST. During the incident, Firebase Cloud Functions that are triggered by Realtime Database events were not firing, which might have impacted automated workflows for customers. While the databases themselves are working, any function that is configured to trigger on certain read/write events may have been significantly delayed and may only have executed after the issue got mitigated. From preliminary analysis, the issue was triggered by an internal backwards incompatible change in a new version rollout. Our engineers mitigated the issue by deploying a fix to all affected regions. We thank you for your patience while we worked on resolving the issue.
