When are the server maintenance windows?

When are the server maintenance windows?

SESYNC schedules a monthly maintenance to patch, apply updates, and perform other potentially disruptive activities. The window is calculated each month by adding 9 days to Microsoft’s Patch Tuesday. This allows us to marshal patches released that month from Microsoft, Red Hat, Ubuntu and our other vendors and have enough time to get our systems prepared to reboot for that month’s window.

The maintenance Window is usually a Thursday. Check the list of upcoming maintenance window dates from University of Maryland’s Institute for Advanced Computer Studies to see the dates of the next few scheduled outages.
