GitLab Update: Tuesday, 14-Oct-2025 @ 10:00 AM

On Tuesday, 14-Oct-2025, at 10:00 AM, the CLASSE GitLab will be unavailable for approximately one hour for a series of updates. Please submit a ServiceRequest if you have any questions or concerns.

LNX201 Reboot: Tuesday, 14-Oct-2025 @ 11:00 AM

On Tuesday, 14-Oct-2025, 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.

Upgrading Windows 10 to Windows 11

In September 2026, CLASSE-IT will be ending general support for Windows 10 to ensure compliance with Cornell University Policy 5.10: Information Security. To prepare for this transition, we will begin reaching out (via CLASSE-IT tickets) to users of CLASSE-managed Windows computers to schedule an upgrade from Windows 10 to Windows 11. This upgrade will wipe the contents of local hard drives and, in most cases, can be finished within a day. Some older computers are incapable of running Windows 11 and will need to be replaced. If you would like to proactively schedule a Windows 11 upgrade, please submit a ServiceRequest with convenient dates and times in the two weeks following submission of the ticket.

macOS Tahoe Release

Apple has officially released the macOS Tahoe (macOS 26) operating system. However, CLASSE services have not yet been evaluated for compatibility with this new operating system, so we are not upgrading CLASSE-managed Macs to Tahoe at this time. Furthermore, Apple has dropped support for macOS Ventura (macOS 13), so we are upgrading CLASSE-managed Macs to newer operating systems as necessary, for compliance with Cornell University Policy 5.10: Information Security.

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.
