Diversity - was: Fiber cut in SF area

Agreed. 

But bear in mind that DWDM infrastructure that does 80 to 120 waves per fiber pair is very expensive.

Sure, the capex cost of offering full diversity is substantial; my point 
was just that the cost of switching STM64 signals at the endpiints need 
not be a significant issue, since you only have to switch the optical 
path, which is cheap to do and highly reliable, and the kit to do that 
will only make up a tiny fraction of the rest of the capital and 
operations cost.
