I am not sure i understand.  Just last week there were many installs
going wrong - installs failing due to the http/https redirecting.
I've got at least 3 occassions myself in the last months where i couldn't 
use pypi.python.org and i've heart similar things from other people.
There is also the issue that it's not clear we could just put all packages
from download locations to pypi.python.org due to sizing constraints - 
at least that is what i got from discussions here earlier.
