The guix-download test includes this snippet:
------# Make sure it fails here.if guix download http://does.not/existthen false; else true; fi------
Unfortunately, many ISPs (such as T-Mobile) return bogus results forotherwise unclaimed domain names, causing this test to fail.
Does anyone know if there is some domain that is designed to fail as a"standard", as http://example.com is intended to be used for examplesof good domains?

Could we simply mock the expected response?

http://fail.0
fails to resolve with "ping: bad address 'fail.0'. This was run on an OpenNIC connected computer.

Yes, this has been reported several times in the past and marked as“wontfix”. :-)

There’s an RFC defining example.org et al. These domain names areguaranteed to exist, so we’d be testing something different; also, Idon’t know if the RFC defines pages guaranteed to be 404, for instance.
