That's not very likely, and if something does change it will be extremely
well announced and documented.  Amazon is providing a commercial service
lots of people rely on, their process is formalized and professionalized.
And if Amazon makes mistakes they'll figure out how to avoid them next time,
while mirror providers are a rotating crew that is unlikely to easily or
reliably learn from past mistakes.  If we actually understood each time PyPI
broke and fixed it none of this would be a problem; I'm not blaming anyone
for that, but it's also not going to change and adding lots of mirror
systems just adds more systems with exactly the same management problems
that our current system has.
