Compute Farm Outage: Ongoing

The CLASSE Compute Farm queues are currently disabled in preparation for an upgrade to the network and to the SGE queue management software. Submissions of new jobs will be suspended until the upgrades are complete on Tuesday, 22-Jan-2019.

Wilson Lab East Module Network Outage: Tuesday, 22-Jan-2019 @ 10:00 AM

On Tuesday, 22-Jan-2019, at 10:00 AM, we will be upgrading the network to the Wilson Lab East Module to a 40 Gb fiber connection. During this upgrade, the CLASSE Compute Farm and users in the East Module will have no network connections. Since this upgrade includes a small reconfiguration of the central CLASSE network switch, there is a chance that internal CLASSE networks will also be affected. If we encounter any problems, we will roll back the changes so that network service is restored by the end of the maintenance window at 12:00 noon.

Upgrading Windows 7 to Windows 10

As mentioned in a previous newsletter, CLASSE-IT is ending general support for Windows 7 on 01-Jun-2019, less than five months from now. All Windows 7 computers will be disconnected from the CLASSE network at that time. We have been contacting Windows 7 users to schedule an upgrade to Windows 10 (or to discuss other options). Some older computers are incapable of running Windows 10 and will need to be replaced. If you have not been contacted yet, please submit a ServiceRequest -- it is important not to wait until the last minute to start the process. You may also request a new computer using our NewComputerForm. Thank you!



General network and server maintenance will occur every Tuesday from 12 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 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.
