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 co=
st*?
