During some debugging of another test I submitted a few commits back to back and encountered the error bellow. It essentially means that we hit a quota for downloads from https://eutils.ncbi.nlm.nih.gov over a certain period of time and this caused the test to fail.

I don't think that there should be a unit test that depends on an external resource with a quota as this can cause failing builds when there's nothing actually wrong with the build.
