Then you probably haven't been on the ass end of a continental fibre link drop. That actually mattered.
If both sides of your SONET ring drop, then surely you're as dead in the water as you would be if each side of the ring was being used as a separate, unprotected circuit.
(But quite possibly I'm missing your point.)
Well, the "someone goes and uses as much of their link capacity as they can, then they lose a 10ge circuit, and suddenly everything is degraded beyond usefulness." I'm way, way out of the loop with such things these days, but the few times this has happened on a specific Perth <-> Sydney circuit which almost everyone seems to use, -everything- degrades. As in, Perth seems almost completely isolated from the rest of the country. I'm very surprised said "O" provider doesn't have a redundant path for all the MPLS tunnels that happen to go over it. :) Adrian
