I'm pretty confident, sitting here on a different continent, that I wouldn't have that problem at all.

You might have that problem, but us-east-1 going dark is unlikely to impact my Australian carrier enough to knock cellular service out. But granted, I might notice something is up if I tried to use my phone for much. If us-east-1 vanished at the right time of day I might notice on my phone first, sure.
