The NixOS Cache is now hosted by Fastly!

I’m getting download errors on nearly every NixOS upgrade since the cache moved to Fastly. The build will fail in most cases. After trying again a few times those errors vanish most of the time. This is very annoying though.

For instance:

warning: unable to download 'https://cache.nixos.community/fhacan05grksvb2k5v4qas19yf6q99qy.narinfo': Error in the HTTP2 framing layer (16); retrying in 261 ms

Any chance we can find out what’s going on here?
