Good point and we would definitely want to avoid that kind of thing.

However, couldn't we use pinning to assign apt sourcing priorities so that if
the first option (proxy) becomes unavailable for some reason the client would
roll to the next priority source?

When I switched to Debain Wheezy (Stable), Rick Moen pointed this out to me

the right packages with less concern of dependency problems. I may still have
those emails if the concept is of interest.
