Patrick,

I'd contend that using Cogent is a good way to reduce your cost of
doing business while maintaining an acceptable level of service, not
to necessarily improve reach. If your network absolutely must have the
best routes you may be better off adding some other providers
regardless.

Best regards, Jeff
