Immediate load reduction

Scheduled for Monday 15th February 2021 at 15:00 (Central Time (US & Canada))

Schedule/description of work

HCC has begun taking action to immediately reduce the power consumption of resources in the Schorr, PKI, and Walter Scott datacenters. Given the extreme temperatures, local utilities have put out an emergency call to reduce consumption, and in some cases have begun rolling blackouts to reduce usage.

HCC will be powering down most of its general access resources, including Crane, Rhino, and Anvil. This will mean all running and queue jobs will be stopped. While we realize this is a major inconvenience, given the extreme circumstances, the well being of the local communities must come first.

Please refer to for further updates should the main HCC website become unavailable.

Scheduled start time

2 days 20 hours


HCC has begun restoring systems to normal operation. Jobs that were running at the time of the outage should be checked and will likely need to be resubmitted. Jobs that were queued should have survived intact, but all users are encouraged to double-check the state of their jobs. Please note that wait times may be longer than usual until the backlog of jobs subsides. Jobs may also briefly enter held states or show a different status than usual before completing. Please allow 24 hours for the queue to stabilize before contacting support about a job's status.

HCC thanks everyone for their patience during this unprecedented event. If you have any further questions or concerns, please contact
