No, it would not have helped. Assume the prospective customer has a link to UUNET and a /24, but wants a second link for [insert reason]. He now goes to and asks for info on getting a second T1. Then the Sprint sales guy calls him and mentions that IF AND ONLY IF he buys a line from Sprint, will Sprint hear his /24.

Of course, even if his line to UUNET is down, UUNET is still announcing the larger CIDR, which is heard by Sprint, and UUNET re-route any traffic destined for that /24 to But that is lost on this prospective customer (if it was ever explained at all - which it definitely would not be from the Sprint sales guy). All he hears is that one of the largest networks in the world will not accept his announcement.

NOTE: I am not saying this is good or bad, simply saying that what you suggest would not be useful in this situation.

Or perhaps they realized this would hurt those prospective customers. Or perhaps any of a 100 other reasons.

"I realize that this is hard for you to wrap your brain around," but please believe there may actually be other people on the planet who have the brains to understand what they are doing and perhaps make a different decision than you made for a good reason.
