Sprint internal inconsistency?

Sun Apr 16 18:21:26 UTC 2006

  I suspected as much myself with regard to not routing customer serial 
links, but I've turned up half a dozen Sprint peering sessions in the 
last six years and I've never seen one act the way this one does.

  Maybe its something I'm doing ... I'm going to take the kids to the 
park and not think about this for a while. Thanks for the response.
