I ran across this test when looking at especially slow files in the test suite: it turns out that not only is this service currently down, but the snakebite.net domain still exists, and as a result the test can end up waiting 20-30s before learning that the hosts can't be found and the test gets skipped.

I agree with Benjamin's and Victor's comments -- the best solution would be to recreate the test, ideally as something that anyone (anyone with Docker installed, perhaps?) can just run locally.

For now I've just sent GH-15349 as a one-line fix to skip the test, with a remark pointing at this issue. It's already getting skipped 100% of the time thanks to the handy `support.transient_internet` mechanism -- this just makes the skip (a) explicit in the source code, and (b) a lot faster. :-)
