GitLab Updates: Tuesday, 07-Dec-2021 @ 10:30 AM

On Tuesday, 07-Dec-2021, at 10:30 AM, the CLASSE GitLab will be unavailable for approximately one hour as we apply a series of updates. Please submit a ServiceRequest if you have any questions or concerns.

CLASSE Network Outage: Wednesday, 15-Dec-2021 @ 9:00 AM

On Wednesday, 15-Dec-2021, from 9:00 AM to 12:00 noon, there will be a general network outage for a central firewall upgrade. Please save your work to samba (central filesystems) and log out of your computer before this time. During this network outage, CLASSE resources and websites will be inaccessible from offsite (e.g. computers at home or on Cornell's RedRover/eduroam wifi). If you are onsite, computers on wired ethernet connections will experience disruptions, although Cornell's RedRover/eduroam will remain available for wireless devices. Please submit a ServiceRequest with any questions or concerns, and consider subscribing to the CLASSE-IT-NEWS-L mailing list for additional announcements and information.

macOS Mojave Deprecation

Beginning this month, Apple and CIT have stopped supporting macOS Mojave (10.14). If you have a CLASSE-managed Mac running macOS Mojave, you will receive an email asking you to schedule a macOS upgrade. We have already seen some problems with Mojave security updates that make it impossible to log in with CLASSE credentials. To check your version of macOS, select "About This Mac" under the Apple menu () in the upper left corner of your screen. The upgrade process takes around half a day and may require you to bring your Mac to the lab.

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.
