https://cache-test.guix.moe is now available for testing. It currently serves substitutes for #Guix and #Nonguix, mirrored from their official publish servers, retaining signing keys.
This new cache-test server uses mirror-substitutes (and store paths from guix-store-paths) to mirror substitutes from any upstream.
If everything goes well, I'll deprecate existing setup on guix.moe mirrors and deploy the new configuration. Feedback welcome!
