Casper returned to service after systems maintenance

October 16, 2020

CISL staff completed the final maintenance and system updates on the Casper cluster Thursday at approximately 9 p.m. MDT and the system was returned to service. Users should access Casper’s login nodes via casper.ucar.edu. Cheyenne was returned to service on Wednesday. This was the last scheduled maintenance window for 2020.

JupyterHub remains unavailable but is expected to be returned to service later today. Until JupyterHub is restored, users can start their own JupyterLab sessions via the terminal if Notebook access is needed. See our documentation for more information.

CISL thanks everyone for their patience and cooperation through this week’s scheduled maintenance downtimes on both Cheyenne and Casper.
