 Not sure where to report this and if it's not somehow related to where I
 connect from:

 `https://github.com/facebook/zstd/tarball/v1.3.8/zstd-1.3.8.tar.gz`:
 {{{

 If github has a habit of re-generating tarballs maybe the github PG should
 fetch from there first before falling back to the mirrors?
