Update:
Email from JGI SysOps and NERSC.
"This public safety power shutdown is unprecedented for Berkeley Lab and for northern California.
PG&E has informed us that once power is turned off,
it will remain off until PG&E crews can inspect power lines and repair any damage,.
A process that can take days.
At this time, it is unclear when NERSC will be able to return to service.
We appreciate your patience in this unpredictable time."
Even if the news says power is back. It can still take several more days before JGI / IMG can resume normal operations.
