- who is operating cache.nixos.org?
- who decides which derivation gets built and cached?
- is there a mailing list that tracks the decisions made by those operators?
It’s operated by the NixOS Foundation, though cache.nixos.org is backed by an S3 bucket sponsored by Infor, and served by a CDN sponsored by Fastly. There is no mailing list, but most of the infrastructure is defined here: GitHub - NixOS/nixos-org-configurations: NixOS configurations for nixos.org and its servers
