Any Qwest routing engineers?

I hate doing this, but I'd appreciate it if someone who can look at routing issues inside AS209 would contact me. We're not a customer, but one of our customers noticed they (actually, our whole network) couldn't reach one of your multihomed customers. Traces stop at chi-edge-25.inet.qwest.net.

Rerouting the traffic to avoid AS209 "solved" the problem...but perhaps we can get the real problem found & fixed?
