Virtual Machine Maintenance - Wednesday 04-Apr-2018

Starting at Noon Wednesday, 4/4, the main CLASSE Virtual Machine infrastructure will be upgraded and rebooted. This should be transparent, but if things go wrong you may see brief outages of the following services:

Linux Kernel and NVIDIA Driver Update

New kernels and nvidia drivers have been pushed to all CLASSE linux boxes. To start using the updated kernel and driver, please reboot your workstation at your convenience.

General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.

Unless other arrangements have been made, CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see SystemExpectations.
