Simple math. The cost of the occasional SLA credit and/or circuit regrooming when the customer discovers a non-diverse path where one was specified is obviously much less than the cost of tracking, maintaining ( and surely providing ) path diversity. Surely large providers have spent a lot more time and money developing processes and software that allow them to groom circuits into the least number of physical paths possible. Or at least I would, if I were paying for the facilities. matto --matt@snark.net------------------------------------------<darwin>< The only thing necessary for the triumph of evil is for good men to do nothing. - Edmund Burke
