Scheduled - During the maintenance period we will be enacting a policy change to the way users access Blanca nodes. Jobs will be held during the maintenance. After the maintenance period only users who have a job running on a node will be able to SSH into a node. This is in an effort to keep users who don't have a job on the node from still accessing it, and to bring the Blanca Slurm policies in line with Summit.

Scheduled - Starting at 5:30 a.m. tomorrow (Wednesday), CU OIT will be updating a number of campus firewalls (the second of two updates) which will make the wired network and many of the campus’s online services unavailable for approximately 50 minutes.

What wasn’t clearly communicated to us in the first version of the service alert was that CU Boulder’s Federated Identity Service will also be affected by the maintenance. The Identity Service provides authentication services for the RC login nodes, DTN, EnginFrame, and RCAMP. This means that new CU logins to these services will likely not be possible during the maintenance. Those already logged in should be unaffected, and jobs should continue to run as normal.

We'll review the status of these services first thing in the morning to confirm that there are no lingering outages.

Sorry for the late notice.
