I have an up-to-date Guix but am unable to fetch the substitute from
  http://ci.guix.gnu.org/build/1332269/details

Are substitutes only available after the evaluation has completed?

So the link indicates that the build has succeeded "19 hours ago",
which would mean on May 9 around 14:30 UTC, which was about an hour
before you wrote this message.

I think the substitute not being available may have to do with the
difference between the package being available in the store, and as a
nar file for substitution. As I understand it, the first request for a nar
can fail, then it is built in the background, and a later request after
a timeout will succeed. Hopefully offload specialists can correct potential
misconceptions on my side ;-)

A later attempt successfully downloaded the substitute. This
explanation sounds plausible, and it is a large package which would
explain the extended delay.
