I've been bitten by this a few times as pypi was down. I still do this, but I'm thinking about setting up some private hosting for the libs I need.

"Private hosting" in this case, can be as simple as a plain-jane Apache server with some tarballs in a directory with listing turned on. Use -f to point pip to the directory. Instant private hosting. This is more or less how we publish internal libraries at work.

you don't need pypi to use pip.
