Perhaps you would like to share exactly what you told the MCI NOC and what
their response was? (offline of course, where it should be)
BTW: I would also be interested in knowing the source and destination
addresses you were having problems with.

Thank you, I will ignore the second sentence.

Yes, circuit numbers usually determine if a person is a customer of
provider X or Y that is calling to utilize provider Z's resources.
Generally, it is a good practice to inquire about problems with the service
provider that provides you services.

Perhaps an emergency maintenance was happening as a result of an unforeseen
outage as I doubt a large service provider would schedule maintenance on a
Sunday afternoon.

The last time I recall MCI uses their customers circuit ID to open a
service inquiry with. They generally don't open tickets for non customers
that can't get to although, my experience is that they are
generally receptive to a notification of a possible problem that may be
occurring within their network.

I respectfully disagree with that statement.

Does this mean you think MCI's use of the Cisco default for route dampening
should be adjusted?
