LNX201 Reboot: Tuesday, 07-Apr-2026 @ 11:00 AM

On Tuesday, 07-Apr-2026, at 11:00 AM, we will be rebooting LNX201, our general purpose Linux login node. As a reminder, please use LNX201 only as a landing pad and for basic productivity tasks. All CPU and memory intensive jobs should be submitted to the CLASSE Compute Farm. Please submit a ServiceRequest with any questions or concerns.

Reboot Your Linux Computers

If you have been issued a CLASSE Linux desktop or laptop computer, please reboot it as soon as possible to activate the updated kernel and drivers.

MacOS Tahoe 26.4: Safe to Update

As a follow-up to last week's Newsletter, it will be safe to update your CLASSE-managed Mac to macOS Tahoe 26.4 tomorrow - Tuesday 07-Apr-2026. The CLASSE Mac management software (JAMF) is set to delete problematic audio drivers, and will notify you when it has done so and instruct you to reboot. Until this is done, you may experience stability and performance issues with 26.4.

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.

The BeamPASS application receives bug fixes and new features on Tuesdays. When these updates are made, users will be logged out but should be able to login again within a few minutes. If you find BeamPASS is unavailable for longer than that, please submit a ServiceRequest.
