Hi Owen,
Generally speaking there are zero or one settlement free peering
points in the active path between any two edges. Not always, but close
enough to it to discount the exceptions.
Speaking for my own experience, I almost never see loss on my Verizon
FiOS edge but see loss at the various Verizon borders with other
networks -all the time-. They keep pitching me on upgrading to 75/75
but that isn't the upgrade I need.
