Eight or nine people I had talked to thought they had geographically distinct ring loops that turned out to be on that one cable when the second cut took it down hard.
Perhaps now people will begin to take physical separacy seriously and write grooming protocols and SLAs into their contracts?
Or was this type of service "good enough"?
What was the actual cost of this outage to operators in SLA credits? Perhaps it's just a function of economics: it's cheaper to plan for the 3 fiber cuts per 1000 route miles per year (or whatever the silly rate was I came across somewhere) and hand out credits than actually engineer physical redundancy. But seriously, has anyone quantified what this or similar cuts *actually cost*? aaron.glenn
