UMIACS takes a monthly maintenance window to patch and reboot our hosts. This provides a way to ensure security updates are installed and activated on the numerous different platforms and appliances that we maintain.

The window for each month is calculated by adding 9 days to Microsoft's Patch Tuesday to allow us to marshal patches released that month from Microsoft, Red Hat, Apple, and other OS and application vendors and have enough time to get our systems prepared to reboot. This translates to the window being on the Thursday that occurs between the 17th and the 23rd (inclusive) of each month. The window lasts from 5pm-8pm. A list of upcoming maintenance windows is as follows, with the upcoming window in bold.
