"available somewhere" until they get moved or deleted...

This happened a few times with archives/artifacts Avocado tests fetch.

We ended up committing one or a set of URLs pointing to a file, its
usual name and its hash.
If you downloaded the file in time and don't flush the Avocado cache,
you can keep testing.
If it is too late (the file disappeared) and you have time to dig for
such a file online, and are lucky because you found it and its hash
matches, then you can run some tests. As a maintainer I find this
feature useful, and find it worse to lose the ability to test
something that used to work.

My 2¢...
