At 2:26 PM ET, we received a notification from our NOC monitoring that the NMS service which handles registration and call processing on GRR crashed. Active calls on this server did drop, and devices on GRR failed over to ATL successfully.
What Is Affected:
When It Began: 2:26 PM ET
Current Status: The NMS service on GRR is back online as of 2:29 PM ET, and registration for all devices returned to GRR by 2:39 PM ET. At this time, all services on GRR are functioning as expected.
Next Steps: We will be monitoring GRR for 24 hours per our major incident policy while we continue to investigate the root cause. If additional outages occur, we will manually redirect devices & calls on GRR to ATL until the problem is resolved.
Next Update: 6/6/25 3:00 PM ET
