Government channel has been running KUAF along with its calendar of upcoming events since about 9 a.m. Sunday. When staff members come to work on Monday morning, I am confident they will put it back on schedule.
There is no way to make up whole day of scheduled programs, but maybe anything you saw on the schedule and wanted to see will be running again this week. Please check the schedule for the rest of the week. Outages during the weekend aren't frequent.
