You'd be surprised. Middle of the night is when big companies do mass
transfers to branch offices, etc. If you go to (what used to be) Hughes's
website, it's full of promo material about how you can distribute sales
videos, update inventory databases, etc., overnight. It was originally very
much pitched as a service where the satellite served as a link between
caches, and so the long latency for the trip up and back to the bird wasn't
a big deal, and for one-to-many links, the uplink (to the bird) bandwidth
was essentially shared.
This model is still quite common with VSAT (Very Small Aperture Terminal)
based systems.. those dishes you see on top of a gas-station, for instance.
Many businesses have large data transfer needs to many locations, but don't
need interactive response, and renting a transponder for an hour for a
multimegabit per second blast from a satellite is much cheaper than buying a
stack of T1s to every little node.
