I'm not sure I understand: if the PyPI server goes down, the
data will still be readily available on Amazon S3 and Cloudfront
caches - the cronjobs copy over the PyPI server content to S3
and Cloudfront serves it up from there.
And if Cloudfront or S3 goes down, client tools could still
try to access the PyPI server. (I'll add a note about that to
