I suspect that Apple and others did not take the latency and bandwidth
limitations of satellite Internet access into account when developing
their software distribution model - if they took such things into account
at all. If I had to guess, they probably used basic DSL, cable modem, or
4G LTE service as their lowest common denominator. I would guess their
assumption is that the vast majority of people who own iThings have an
equivalent kind of Internet connection at their disposal. I'm not saying
that's right or wrong, but I wouldn't be surprised if that's their
I fully understand that it's very difficult and expensive to evolve the
orbiting pieces of your network to get more bandwidth. Designing,
building, flying, and operating a new bird is obscenely expensive.
Higher data rates impose limitations of their own, re: rain fade, etc,
plus the CPE might need to be replaced.

What happened is not an unprecedented occurrence. I used to work at an
ISP, and I remember our customers crushing our pipes during an infamous
Victoria's Secret webcast many moons ago. Many websites for major news
outlets seized up on 9/11 because they couldn't handle the number of
requests that were coming in. Joe Schmoe's website blows up because
he was featured in an article on Slashdot. That was before the days when
geographically dispersed content distribution became commonplace and
websites weren't nearly as content-heavy as they are today.

I won't disagree (happy with my fios service, other than the complete
inability to get a straight answer from anyone in charge re: when IPv6
will be available in my area but that's a topic for another thread), and
yes, I do remember 9600 bps modems. I started at 1200 bps, and my first
reaction when I got a 2400 bps modem was 'Holy crap is this fast!' ;) For
some reason, I recall the jump from 2400 to 14400 'feeling' somewhat less

I didn't have a hard drive with enough space to store 100 MB of anything
at that point ;)
