I would like to thank Donald Stufft for doing much of the heavy lifting on the PyPI side, and to Fastly for graciously offering to host us. What does this mean for everyone? Well the biggest change is PyPI should get a whole lot faster. There are two major downsides however. There will now be a delay of several minutes in some cases between updating a package and having it be installable, and download counts will now be even more incorrect than they were before. The PyPI admins are discussing what to do about download counts long-term, but for now we all feel that the performance and availability benefits outweigh the loss. If anyone has any questions, or hears anything about issues with PyPI please don't hesitate to contact me.

One addition. Eventually PyPI will move towards using the Fastly API for cache invalidation so that uploading a new package _will_ be immediately available. But that was deferred in order to get the larger benefit *now*.
