Scientific Linux 7 Deprecation

In preparation for the end of support for Scientific Linux 7 (SL7) on 30-Jun-2024, we will be upgrading all CLASSE Linux systems to AlmaLinux 9 over the next few weeks. If you have a CLASSE-managed Linux desktop or laptop system, we will contact you via a ticket to schedule the upgrade. Please also consider switching from lnx201.classe.cornell.edu (SL7) to lnx209.classe.cornell.edu (AlmaLinux 9) as a general-purpose landing pad.

macOS Monterey Deprecation

Apple has announced that macOS 15 (Sequoia) will be released this fall. At that point, macOS 12 (Monterey) will no longer be supported by Apple. CLASSE-managed Macs running Monterey will need to be upgraded to a newer operating system by the end of 2024 in order to comply with Cornell University security requirements. To see what version of macOS your Mac is running, select "About This Mac" under the Apple menu () in the upper left corner of your screen. If you wish to schedule an upgrade of your CLASSE-managed Mac, please submit a ServiceRequest.

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.
