Cheyenne unavailable today due to NWSC power outage

The Cheyenne, Geyser and Caldera systems are expected to remain offline throughout today, January 3, as the NCAR-Wyoming Supercomputing Center (NWSC) facility continues to recover from the December 30 power outage.

Power has been restored to the NWSC and CISL staff have begun extensive hardware and system software testing to ensure that the systems were not damaged as a result of the sudden loss of power. Every effort is being made to restore Cheyenne, Geyser and Caldera as soon as possible.

CISL will inform users through the Notifier service of any significant updates and when the systems are restored. We apologize to all users for the inconvenience this will cause, and we thank you for your patience.

Also be aware that, as planned, the Yellowstone system has been powered down permanently.
