Based on all that, it looks like Qwest is not propogating your routes
within their network.
I was going to recommend route-views, but it might not reflect that
now if you have dropped GBLX.
Historical routing updates will show though if Qwest were advertising
reachability to you (which would be a good indicator if they were
filtering at their edge)
