The limited data I've seen suggests the download speeds people get from
the substitute servers vary a lot depending on their internet connecting
peering and location, so it's quite hard to consider this in an abstract
sense. Some people already get substitute download speeds that saturate
a gigabit connection, while some don't.

There has been work on setting up mirrors though, e.g. see [1] for some
information and data on how these work for different people.
