Why Use a PyPI Mirror?

In addition to hosting packages, PyDist acts as a PyPI mirror—users access PyPI data through PyDist, which backs up that data so it will never disappear. Why? Because data disappears from PyPI all the time.

Like NPM, PyPI allows package maintainers to delete packages and releases at will. Python has had its own version of the infamous left-pad incident, when the trollius package was suddenly unpublished, breaking dependent packages such as internetarchive, neovim and aiodns until zope foundation volunteers managed to find a backup of the last release and took over maintainership. While Python packages are not as inter-dependent as Node packages, it is only a matter of time before a more widely-used package is deleted from PyPI.

While deleting packages is relatively rare, deleting releases has become a common cause of broken builds for PyPI users who pin their dependencies—especially users who update frequently. If you maintain Python packages, check out the blog to learn how what you should do instead.

Since PyDist launched in March 2019, 32794 releases for 5375 different packages have been deleted from PyPI. Below is a list of deleted releases for the most popular Python packages, updated weekly.
