You always have to specify to the carrier that you want diversity. For longhaul, sometimes even big name providers will subcontract to another provider. For instance, you may get 1 OC-3 from MCI and another from Sprint, but both might be going through the same Qwest OC-192 from Denver to San Jose. I've seen it happen and it's always ugly for the buyer when someone backhoes it. You have to specify and sometimes pay more to be certain of your diversity.

If someone is homed to 2 different providers, and 1 circuit goes down, the other should keep them up.

I'm still awaiting the list of providers that never have a circuit go down. :-)
Every carrier has had a circuit go down.
On that we agree.
The difference is the carrier's response, in particular how well they keep their customers informed.
That is certainly *a* point of differentiation, however if the goal of these "basement dual-homers" is to not suffer downtime due to the outage of a single provider(much like the organizations that "matter"), all the responsiveness in the world from a provider whose circuit to one of the "basement dual-homers" which has failed isn't going to prevent them from being down, is it?
