At 11:59am today WorldCom lost 6 major ATM trunks from St. Louis to L.A. So as you can imagine... MANY MANY ISPs are in some state of down. Just letting you know. No time estimate to repair has been made.
Ya, we are going to kill worldcom for this one, they say they have 496 DS3 connections down. We have 3 connections into our Palo Alto POP, and Worldcom said they all are over different fiber paths. As of right now they all are down. Nathan Stratton President, NetRail,Inc. ------------------------------------------------------------------------ Phone (888)NetRail NetRail, Inc.

Path diversity is not something obtained and then safely assumed forever. It must be monitored with dilligence, and this is far from trivial, even for L1 geeks. randy

You should never trust what your sales people say. When designing your backbone, its important to ask them for your DLRs (design layout records) so that you can see physically, with your own eyes, the paths involved. -Golan

I know this, I have a copy of the DLRs. What I am saying is Worldcom changed the DLRs without letting us know, and now they all run over this fiber cut. We request a copy of the DLRs on ALL our links. We started this long ago when we had a MCI and Worldcom DS1 die because they went over the same fiber.

And you haven't checked since? In my experience, path redundancy doesn't stay that way. Either the first or second round of grooming in carrier network eliminates the path redundancy, and I don't know if it's possible to win against the transmissions people about that.. We've fought with carriers about that for a very long time, and didn't get anywhere.. -dorian

Yes, the last time we checked was a little over a month ago. They show the DLRs were changed last Friday.

Shouldn't/Don't carriers flag paths that are part of path redundancy links to avoid automatically re-routing them? Cheers, -- jra -- Jay R.

Worldcom changed the DLRs without letting us know
happens all the time. they do that like we move customers between router ports. if you want to maintain path diversity, you have to continually monitor it with your carriers. and then you'll need to go out and physically every once in a while. yes, this is major major pain. randy

I don't know if it is related, but the Internet today has gone to a slow crawl, but this could be just UUNet. I was trying to get a site today and only getting maybe 33bytes/sec.
