A friend works for Uncle Sam, and he is required to audit the
routes used on certain high-availability systems, to insure the
diversity we pay for. (It's in the contracts with the carriers..)
He describes it as a long drawn-out exercise in futility. A
non-trivial employee has to spend eons on the task. It's a recursive
onion peeling, or a data version of Tom Lehrer's "I Got It From
Agnes"...
And once done... the errors found, the diversity restored, and the
report signed off; it's soon worthless...because the carriers
soon shuffle things around Yet Again.
And I agree re: the building entrance issue and later choke points.
Anyone recall the time several years ago that most of the Valley was
isolated? One route was across the ?Bay? Bridge; it was down for
planned maintenance when backhoe fade struck around San Jose.
How many paths is enough?
