This URL here:
https://tests.reproducible-builds.org/debian/winswitch
doesn't redirect to:
https://tests.reproducible-builds.org/debian/rb-pkg/stretch/amd64/winswitch.html
as it should.

The package has been removed from unstable, and it's now available only
in stable (stretch).

I believe I see similar instances of inabilities of redirects in other
cases in the past, like for testing-only packages maybe?
