PEP-449 [1] describes the 'Removal of the PyPI Mirror Auto Discovery and
Naming Scheme'.
The main elements of this (Accepted) proposal are:
- Removal of [a-z].pypi.python.org DNS CNAMES
- Replacing individual mirrors with a single Geo-aware CDN service
Previous revisions 365159, 347895, 342514 deprecated several individual
mirrors and *.pypi.python.org aliases. The following changes (Part III)
completes the (PEP-449 compatibility) transition:
- Remove pypi.crate.io (NXDOMAIN)
- Remove pypi.python.jp (Outdated)
- Switch to TLS (HTTPS) MASTER_SITE by default
- Leave a non-TLS (HTTP) MASTER_SITE for fallback (proxy environments)
