It's already changed again:

I can check my substitute server tomorrow for the ‘original’ 
(091cizxg1aw8bkj58y048mj020ssapjflav633z9bl6gmi10dy4v) tarball if 
nobody else has a copy.  Guix servers don't seem to.

If someone is trying something sneaky, they're making an 
incompetent amount of noise about it.

Looks like upstream's just gone a bit timestamp-crazy, judging 
from the small handful of (very recently) mirrored tarballs I 
could find:

/gnu/store/26akldw7c2y6fparfixycdb0lhds8ddj-elixir-mode-2.3.1.tar

 [the current canonical upstream tarball, I guess, mentioned 
 above]

which differ[0] only in metadata:
