Unrelated but made me think of this anecdote; Many years ago I met a tech-savy captain who did have satellite internet on his ship, but it was incredibly expensive (not sure about current pricing), so he only used it briefly every now and then. To receive e-mails (and some other things) he had a server somewhere which fetches everything and then zips it up as compressed as possible and when online synced it to a local computer/server that's onboard.

It was pretty fun/interesting to see creative solutions like that to deal with very limited bandwidth in practice.
