Richard Jones' Log: Introducing pythonhosted.org - the new packages.python.org
We've just added a new domain to the python.org stable, pythonhosted.org, to replace the existing packages.python.org domain. All accesses to the old domain are redirected to the new - all existing references will work. Google et al should catch up eventually.
This was done as part of an overall review of security of the PyPI website. Warning, that thread is longish :-)
