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
