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.

Think about your last statement. 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?
