I wonder if there is a solution, in general to diverse physical
routing... if you buy from multiple carriers, they might very well share
the same fibre condo, or the same dark fibre vendor.  if you buy
diversity from one vendor, with only handwaving as the guarantee, you
end up with Bell Canada's CO fire a couple years ago, that took down
things which were *supposed* to be redundant.

What are people's experience with knowing the physical routing?  NetNod
may be over-the-top secrecy wise, but are *any* carriers/facility
providers any more "free" with information about the details of where
their infrastructure is that supports the services you are buying?

It seems the general practice is to claim everything is on a
need-to-know basis, with the unspoken/unwritten caveat that nobody's
needs will ever be considered valid?
