GitLab Update: Tuesday, 30-Sep-2025 @ 11:00 AM

On Tuesday, 30-Sep-2025, at 11:00 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.

BitLocker Recovery Keys

Following a recent Windows security upgrade, some CLASSE-managed Windows computers are occasionally asking for a BitLocker recovery key in order to restart. If you encounter this message, please submit a ServiceRequest with the name of your computer, and we will securely provide you with the key as soon as possible.

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 the Cornell University Policy on Information Security.

[PSA] Scientific Computing Training

Cornell's Center for Advanced Computing (CAC) and Weill Cornell Medicine's Scientific Computing, ITS, and Clinical and Translational Science Center is offering a Scientific Computing Training Series that is open to all workforce members and students of Cornell University, WCM, WCM-Q, and Cornell Tech. Upcoming topics include HPC job optimization (30-Sep-2025) and an overview of AI (07-Oct-2025). The slides and recordings of the training presentations are posted on the website.

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.
