ARTIFACTORY: Crates.io Download Changes

The crates.io registry, a central hub for Rust packages, recently implemented a change to improve package delivery efficiency. Their config.json configuration file now points to a Content Delivery Network (CDN) for certain resources. This shift offers faster and more reliable access for users around the globe. For more information, see Crates.io: Download changes. 
However, a minor wrinkle exists for users who leverage JFrog Artifactory as a remote registry when using the Cargo Remote Repositories. Caches containing unexpired packages might still reference the old, non-CDN URLs in the previously downloaded config.json file, meaning that they would not benefit from this update.

Mitigation Steps 

To ensure these cached packages benefit from the crates.io CDN update, simply reindex the remote repository. This process will fetch the latest config.json file containing the updated CDN references. With the reindexed repository, cached packages will automatically utilize the faster CDN delivery.

Overall, this change by crates.io signifies a positive step towards optimized package delivery. By reindexing your remote repository, you can seamlessly take advantage of the CDN improvements.
