Sure, we could do all those things, but such a process will
cause a lot of admin overhead on part of the PSF.
Using a content delivery system we'd avoid such administration
work. The PSF would have to sign agreements with 10-20 mirror
providers, it wouldn't have to setup a monitoring system, keep
checking the mirror web content, etc.
Moreover, there would also be mirrors in parts of the world
that are currently not well covered by Pythonistas and thus
less likely to get a local mirror server setup.
How to arrange all this is really a PSF question more than
Also note that using a static file layout would make the
whole synchronization mechanism a lot easier - not only
for content delivery networks, but also for dedicated
volunteer run mirrors. There are lots of mirror scripts
out there that work with rsync or FTP, so no need to reinvent
AFAICTL, all the data on PyPI is static and can be rendered
as files in a directory dump. A simple cronjob could take
care of this every few minutes or so and extract the data
to a local directory which is then made accessible to
Professional Python Services directly from the Source (#1, Jan 21 2010)
