We have sunset the original Python Package Index service, which was temporarily deployed at https://legacy.pypi.org .
The new PyPI is at https://pypi.org . Browser and API calls to pypi.python.org will continue to redirect to pypi.org .
If you have been using legacy.pypi.org directly, please start using pypi.org : https://warehouse.readthedocs.io/api-reference/integration-guide/#migrating-... If there is a feature that the new codebase does not support, you should file an issue at https://github.com/pypa/warehouse/issues as soon as possible.
If you use JFrog Artifactory, please make sure you're running the latest version. Please see the guidance from JFrog https://jfrog.com/knowledge-base/why-am-i-not-able-to-connect-to-pypi-python... and full discussion of the issue https://github.com/pypa/warehouse/issues/3275 .
