The cut is a complete cut of a 108 fiber bundle between Yuma, AZ and El
Centro, CA. L3 reports it is a very isolated area with no roads, making
any access very difficult and slow. The last estimate we received at
23:37 EST (20:37 PST) was 3-4 more hours with the proviso that "Estimate
may change depending on circumstances on-site."
