AlmaLinux 9

On 30-Jun-2024, Scientific Linux 7 (SL7) will reach its end-of-life and will no longer receive updates after that date. CLASSE-IT recommends and is supporting AlmaLinux 9, a rebuild of RedHat Enterprise Linux 9 (EL9), as a successor to Scientific Linux 7. A new CLASSE AlmaLinux 9 login node (lnx209.classe.cornell.edu) has been deployed and is ready for use. Please consider switching from lnx201.classe.cornell.edu (SL7) to lnx209.classe.cornell.edu as a general-purpose landing pad. As previously announced, the Zoom desktop client will stop working for Scientific Linux 7 starting 04-Nov-2023.

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.
