This incident has been resolved.

We believe the incident was fully mitigated as of 11:40pm.

We are starting to see some recovery.

Mitigation work is currently underway by our engineering team. We do not have an ETA for mitigation at this point. We will provide more information by Thursday, 2026-06-11 03:00 PDT. Customers may observe requests to send messages to FCM taking longer to complete. A small number may experience 5xx errors and should retry with backoff.
