The IT Division has scheduled a maintenance period for 5-10 p.m. on 
Tuesday, Jan. 16. During this time, the Division will be making some 
configuration changes to the outgoing mail servers to make them more 
secure; these changes should not impact performance. The wireless 
network environment will also be updated, requiring a brief outage (less 
than five minutes) while the controllers reboot to finalize the update.

In addition, updates to Core Common User Environment software packages, 
such as Firefox and Thunderbird, will be deployed. Also, the Linux VDI 
infrastructure will be updated to a new version; this environment will 
be off-line during the maintenance period. Symantec AntiVirus client 
updates will also be released during this maintenance period, which will 
require a reboot of Windows desktops. If you are prompted to reboot your 
computer to finish the Symantec installation, please do so as soon as 
practical. Finally, Windows and Linux patches will be released to all 
CUE-managed servers and desktop systems, and various Windows and Linux 
services will be unavailable for a short period overnight while the 
underlying servers are rebooted to finalize patch installations. Please 
plan on rebooting your Windows or Linux desktop system no later than 
Friday, Jan. 19.
