Re: Sprint (1239) blackhole ? Or bogus /32 route ?

[Mike Tancsa <mike () sentex net>]

Thanks to all who have responding with information from their network

inside of Sprint. In the interim I made an advertising change to hopefully 
minimize the impact until I hear from someone at Sprint as to what the 
issue is.
