In the last hour I started observing the following loop: https://pypi.org/pypi/nonexistant-package/json -> https://pypi.org/pypi/nonexistant-package/json/ -> https://pypi.org/pypi/nonexistant-package/json
This is breaking pipenv package resolution for us, since we use 2 different indices and it checks for a 404 from PyPI before going on to the second one. I assume any pipenv or pip user relying on multiple indices is currently unable to resolve packages.
