Derecho Downtime February 5–7 for System Maintenance

January 26, 2024

Derecho will be down for scheduled maintenance February 5–7 to perform system software updates.   This is a slight extension of the regularly scheduled February 6th maintenance window. During this outage systems engineers will apply updates to the Cray Programming Environment (CPE) and also the high-speed Slingshot network for performance and stability enhancements.

Our intention is to return Derecho to service Wednesday morning, February 7, however precise timing will be determined by maintenance events as they unfold. 
Progress will be communicated through the Notifier system throughout the course of the outage.
