Both NetworkManager and ConnMan are able to do that, although I don't
know whether that's enabled in Debian. In both cases I think the "am I
online?" URL is configurable, defaulting to one provided by unstable,
but distributors are able to change the default; for instance I think
Fedora configure their NM packages to try a Fedora-hosted URL instead.
