The key is to go with multiple suppliers who can guarantee diverse 
routes.  Carriers lease capacity from each other in some cases, so 
Sprint and MCI can give you circuits in the same physical fiber.

Sprint and AT&T are implementing SONET protection switching which will 
reroute circuits around fiber cuts in 50ms.  I don't know if they do it 
as a rule, or if you need to specify rerouting priority (and pay for 
it).

It's interesting to look at a carrier's fiber map and compare it to a 
railroad map.  You'll see MANY similarities.  Railroad rights of way are 
the easiest areas to install fiber.
