I'm at a multi-POP network in Boston.  We've had great luck selling

Don't know how the world looks like in the US, but here a SDH/Sonet
provider will never guarentee diversity of his/her circuit to that of a
different provider, often the end user can be almost sure that at least
the last few km will be in the same duct, as the local communities
demand that the providers cooperation when digging fiber into the
ground...

It costs more, but they don't have nearly the
exposure of a single circuit customer.  However, if you're not set up to
do this, the appropriate level of paranoia calls for circuits to two
different providers.  Maybe if SPs really addressed availability
requirements of their customers, it wouldn't be such an issue.
