I would imagine its probably sort of like the electric grid. In the morning there is a huge surge as people wake up, flattens out during the day while people are working and goes down at night while most (normal) people are asleep. If it was 'machine driven' traffic I'd imagine it would be pegged constantly, where as bandwidth for a given region of the world would behave similar to that of electricity usage.
