Comment (by chrstphrchvz):

 If I set `macports.conf` to try github.com first, I get the correct
 checksums (I am doing this from San Antonio, Texas):

 This matches the published
 [https://github.com/facebook/zstd/releases/download/v1.3.8/zstd-1.3.8.tar.gz.sha256
 zstd-1.3.8.tar.gz.sha256] file on their fancy (not-automatically-created?)
 [https://github.com/facebook/zstd/releases GitHub releases page].
