Here you go Ed, June 13, 1997 11:00 EDT. We are experiencing routing instabilities due to bad BGP announcements coming from one of the international network service providers that we peer with in Pennsauken, NJ. These announcements will cause delay and/or unreachable states across the country as the network reconverges around the problem. We have isolated the problem, and are working to clear the bad routes from our network. We apologize for the routing instabilities that you may be experiencing, and appreciate your patience on this issue as we work to resolve it. Thank You Rob Rockell Sprintlink ISC. ->Hi, -> ->I'm seeing some weird routes while going through sprint-nap.

AS 400 started announcing some 8000+ routes some time between 17:00 and 18:00 EDT today. AS 400 is behind AS 568 (DISA). Various folks have now blocked either just _400_ from DISA or blocked all routes with DISA or turned off peering with DISA. Most of these bad routes are now gone in most places. There are still lingering pockets of bad routes due to folks running old cisco code - remember the AS 7700 incident where the bad routes hung around for at least 24+ hours? Cisco has fixed this stuck route problem, but not everyone has upgraded all of their routers. A work around is to clear BGP sessions to get rid of the routes. [I've been on the phone with various NOCs and engineers with Sprint, MCI, Verio (my NOC) and DISA for the last several hours.] --asp@partan.com (Andrew Partan)
