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

Thanks to all who have responding with information from their network vantage point. It does indeed seem to be an IGP or blackholing issue 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.

Looks like something isn't right... I see the announcement from Sprint with an AS path of 1239 852 11647, but it never gets past one of the routers on Sprint's network. I have no problem going through Cable and Wireless:
Yes, and the strange thing is that is just one IP address :-( 199.212.134.9... If you try 199.212.134.1 I bet you can get to it via sprint.

I would contact Sprint. Good luck!
Thanks, I did. Responder robot said they would try to get back to me in 72hrs :-(
