Hex packages, the registry and other files are by distributed (mirrored) in various locations. The choice of mirror can be customized in Hex clients.
Note: By default, Fastly is used to deliver the files. Fastly distributes files geographically for low latency and fast downloads.
To permanently select a mirror, simply run the following command in a shell session.
Mix Example: $ mix hex.config mirror_url https://repo.hex.pm
Rebar3 Example: Add to the global or a project’s top level rebar.config, {rebar_packages_cdn, "https://repo.hex.pm"}.. For more information see rebar3’s package support and configuration documentation.
To temporarily select a mirror, Hex commands can be prefixed with an environment variable in the shell.
Mix Example: $ HEX_MIRROR=https://repo.hex.pm mix deps.get
Rebar3 Example: $ HEX_CDN=https://repo.hex.pm rebar3 update
