The ParMetis URL http://glaros.dtc.umn.edu/gkhome/fetch/sw/parmetis/parmetis-4.0.3.tar.gz is down

Is it temporarily down, or is there a replacement URL?

It seems like this URL still works for the tarball:

https://karypis.github.io/glaros/files/sw/parmetis/parmetis-4.0.3.tar.gz

If you happen to be here because you're tracking down a chain of issues with homebrew formulae decaying, use homebrew edit to swap the URL in the formula and it should work!
