That's not true. The client software can check whether a mirror is 
up-to-date, and proceed to the next mirror if one is outdated.

The same can happen to any infrastructure, though. Amazon may decide to 
change the setup, and then the automated update procedure would break.
Of course, they would give advance notice - but then somebody would
have to react to that advance notice.

With the proposed default redirection of all PyPI downloads to Amazon,
such breakage would affect the entire installation, not just a single 
mirror.
