Apologies for the outage.


-------9:01AM December 18, 2023------

The MGHPCC main meter detected two ITIC Level 4 power sag events at 6:39AM on Monday December 18.  The power sag affected all non-UPS systems in the data center

The sag caused a circuit breaker inside the data center to trip, leaving power down on the following pods:
Row 3 Pod A
Row 4 Pod A, B (odd side), and C
Row 5 Pod A and C
Row 7 Pod C
Row 8 Pod C
Row 9 Pod C (odd side)
Row 8 Pod A

We are working to restore power as soon as safety checks are done, and double-checking the status of all other pods.
