The campus Active Directory service, CFS, will be will be undergoing maintenance. There are multiple domain controllers running the service, but one of them will be restarted during the maintenance. The impact of this should be minimal as most services and devices will just switch to use one of the other domain controllers automatically.
Active Directory provides authentication to campus connected computers, access to file and print shares, and authentication to other campus services such as the uog-wifi network and business voicemail.
