Both of these servers compile Haskell packages relative to the 'master'
branch of Nixpkgs. The 'nixos-unstable' channel has been lagging behind
'master' for a while now. My guess is that these packages you'd like to
retrieve have been garbage collected a while ago and are no longer
available.

Generally speaking, it feels a little extreme to call a rebuild of 80
packages a "mass rebuild". I don't know what kind of hardware you're
working on, but a modern machine should easily compile those packages
within a couple of minutes.

Best regards,
Peter
