I know this, I have a copy of the DLRs. What I am saying is Worldcom
changed the DLRs without letting us know, and now they all run over this
fiber cut. We request a copy of the DLRs on ALL our links. We started
this long ago when we had a MCI and Worldcom DS1 die because they went
over the same fiber. 

And you haven't checked since? In my experience, path redundancy doesn't stay
that way. Either the first or second round of grooming in carrier network
eliminates the path redundancy, and I don't know if it's possible to win
against the transmissions people about that.. We've fought with carriers about
that for a very long time, and didn't get anywhere..
