Looking at our bandwidth chart for the last day I can really tell it's finals week.


See that trail-off about 1am last night (Sunday)? That normally starts earlier and bottoms out faster when students aren't up doing finals-related things. I know from watching printing-activity reports for overnights that for the first part of finals week our printing activity between 1:30am and 6am is markedly higher than it is at any other time during the quarter. Bandwidth-usage also increases during this time as they take YouTube breaks and whatnot whilst typing madly. By Friday the chart should be a lot flatter as students who don't have end-of-week finals up-root and leave for home mid-week.
Back on printing, our morning peak starts earlier during finals. During most of the quarter usage starts rising about 6:30am and doesn't really get going until 7:30-8:00. This time of the quarter the rise starts at 6am, and is a lot busier, earlier. The steady drumbeat of mid-terms means that there are usually a couple of people pulling all-nighters starting roughly the 3rd week of classes, but finals really focus everyone.
