Are you being BGP'ed blackholed? Like, one of their routers is lying about a route it owns? At 10:35 AM 1/23/98 PST, you wrote:

We just being blackhole by some ISP during their provisioning, a few hours ago. I thought that bogus route should be filtered by the NAP. Is there a way to prevent from somebody blackholing you ? It takes a lot of affort to solve this problem, especially those who need to update their router through rrdb automatically. Which suppose to solve blackhole problem accidentally.

Could you please explain the issue more specifically. "Blackhole" could have many meanings.
