autopkgtest does not use any specific mirror. It's just calling
"apt-get download", and thus it's using whichever deb source you have
in sources.list. If that is a file:// source, then it won't hit the
network indeed. This is exclusively a problem if you have some kind of
build environment where you put exactly the build deps into
/var/cache/apt/archives/, and then build in an environment without any
network access to pull other packages from. That's why the bug is
still open, but pbuilder, sbuild, cowbuilder, plain debuild etc. all
don't work that way. (Hence "unusual environment").

Out of interest, what are you using as a build env?

Independently of this, that's a good idea to document, thanks!
