The Baltimore Sun has a graphic showing the re-routed fiber optic
line.

I understand all the carriers have people working very hard to fix
the cut, but the question which is rarely asked and even more rarely
answered is where was the physical diversity in those carriers
networks? Did these carriers know about this vulnerability in their
network? When customers asked, were the customers told?
What are MFN or Worldcom sales people telling customers who ask what
happened to their network diversity?
There's an archived story about the history of the tunnel:
http://www.sunspot.net/news/local/bal-traintunnel.story
This is an interesting note for those wondering how the cables were
physically snapped:
"The tunnel also has a second use. An MCI fiber-optic cable trunk line
suspended on the tunnel's west wall carries thousands of long-distance
phone calls."
It seems less than a derailment could cause some damage... I assume(???)
that it's in heavy conduit of some sort, but it seems even some
maintenance or other activities could snag something and cause a similar
outage...

It does not take that much of a fire to melt a 4" conduit.
