The EECS Mailing List server lists.eecs.berkeley.edu will be briefly down for maintenance tonight, Wednesday March 3, 2021, beginning at 6pm.
Routine Red Hat Linux operating system patches have been released which require a system restart. During this maintenance window, the web interface will be inaccessible, and any mail sent to a mailing list will be temporarily delayed until the server resumes operation. We anticipate an outage of no more than 30 minutes but some extra time is being scheduled in case of unforeseen problems.
As usual, please send any questions to help@eecs.berkeley.edu.

Our Terminal Services license manager host, RDSMANAGER, needs to be temporarily taken down so that we can make a repair to the virtual disk image file used by this virtual machine. We will be shutting down RDSMANAGER at about noon on Friday, February 19, 2021.
During this maintenance, any Windows Terminal Servers (such as winterm.eecs) will alert users that no valid Terminal Service license servers could be contacted — but other than the alert, no interruption of service should be noticed.
RDSMANAGER should be down for 4-6 hours. License service should resume as normal by about 6pm Friday.
