4/22,2020, Midnight to 2:00 AM: In order to complete installation of critical security updates, msfs-share and msfs-util will be restarted at Midnight. These servers host the P: Drive, S: Drive, and other network shares. They also host departmental Campusweb pages (sites not hosted in Drupal or WordPress). The restart is scheduled for 2 hours, but it will likely take less than one hour.
