This shows that substitutes were not used:

That’s why you get the exact same result as before.

The reason substitutes were not used is that Guix cached the fact that
substitutes weren’t available.  They became available in the meantime
but the cached entry hasn’t expired yet.

To work around it, you could wait some more :-), or you can do:

  guix pull --substitute-urls=https://berlin.guixsd.org

berlin.guixsd.org provides the same contents as ci.guix.gnu.org.
However, that will trick Guix into building a fresh cache for that
machine.

Let us know how it goes!
