New Orleans fiber optic route

From AP:

The grim TV footage showing a collapsed bridge that once crossed Lake
Pontchartrain, one of the main roadways into New Orleans, make it clear
why evacuations have been so difficult. That bridge also happened to hold
the fiber-optic cables that transported calls and Internet traffic to and
from the city as well.

While every major phone company has been scrambling to patch its way into
the city and other hard-hit areas using alternate routes and backup
equipment, it could be some time before many local phone and Internet
lines are back in service to receive calls and data.
