Here is the page to use:

https://data.guix.gnu.org/compare/package-derivations?base_commit=d7673b49c086c898a8e749fd042081dc9d4631b8&target_commit=cf26ee1f99f84f817f96269541073846d546026b&build_change=broken&after_name=&limit_results=40

When comparing core-updates to master, the base commit should be from
the master branch, and the target commit should be from core-updates.

However, it looks like the Data Service doesn't know about these commits
on core-updates, which is unfortunate.

My understanding is that Cuirass stopped sending information to the Data
Service after this commit was deployed:

https://git.savannah.gnu.org/cgit/guix/guix-cuirass.git/commit/?id=e598f89445b58eede595e66076405931e6bb1e55

So, in the short term, to get useful information about core-updates from
the Data Service, we'd want to build core-updates in Bordeaux.
