I think the potential difficulty is (1). Maybe they take it down (e.g. they move on to version X so they take down old version Y).
An alternative would be to stash a copy somewhere on GHC’s main web server, and wget that. I’d be more comfortable doing that; less dependence on others.
I guess storing a copy somewhere on https://ghc.haskell.org/ should be ok (I'm hoping Austin may weigh in wrt CDN-related considerations). I'd suggest using it as a fallback location though. I.e. try downloading from the official upstream location, and if that fails (either due to I/O errors and/or unexpected checksum), fallback to using our locally mirrored copy. However, we may need to take into account license issues, such as hosting the source-code as well, if we host binary distributions depending on the licenses involved (I'm not sure if this was ever considered for ghc-tarballs.git to begin with) Cheers, hvr
