The Networking team will be upgrading network code at ITDC during this work window.

The Argon HPC service will be down for regular maintenance from 8:00 AM on February 11th until 8:00 AM on February 12th. During the maintenance all jobs will be stopped and users will be unable to log in.

Active sessions will continue to run. There is a small chance that new sessions may not be able to launch during the maintenance window. We recommend logging into IDAS and starting your session before the maintenance window.

ITS Enterprise Infrastructure will be conducting networking updates for the Research Systems located in the ITF Data Center. These updates will result in the following Large Scale Storage systems having multiple network disruptions over the course of the maintenance window. 

Research Services recommends  saving and closing all files stored on LSS before the maintenance occurs to prevent data loss or corruption.
