I have tried running the Attic Nix Binary Cache on my Hetzner dedicated server in Germany a few times in the past, but the peering issues and the latency to Xfinity in Seattle have always made me throw my hands up in frustration. This morning I noticed a comment by Zhaofeng on the repo issue tracker. As a NixOS aficionado myself, I begrudgingly admit that I’ve been running my instance on fly.
