What are MFN or Worldcom sales people telling customers who ask what happened to their network diversity? When they were told they had all five nines covering that network they should have asked where the decimal point was. -g- Looking at that map it makes sense, it's where I'd have run it. There is a lot of cable in those conduits already. The guys I saw on 29th and Calvert Street (about ten blocks north of where that map cuts off) were probably hopping the turn west back down 29th to the train tracks. It's my route home because it pops me onto the on ramp of 83 North. The Expressway (83) and the train tracks follow the canyon created by the Jones Falls (a river). The Jones Falls sort of bisects the West and East side of the City in the north. I guess they were making that left back down to the original cable. I've done a running race from right about the beginning of the re-route up to 31st street and back to the Inner Harbor. It was a 10k so the distance they ran that cable was 3/4 the distance of that accounting for the jogs left and right (4.5 miles). But here's the rub, I doubt they had to pull cable the whole distance because the CO that I'm next to is just two blocks north of where I saw those network guys and all the cable to downtown from it runs under Guilford Avenue (My studio is between Guilford and Calvert). I bet they only had to patch into a redundant cable until they made that turn on 29th back down to the tracks. Looks like Muffin was the hero that pieced it all together: Message 16107618 The video that CNBC showed of them pulling the cars out of the tunnel showed the equipment in the parking lot of that train station building that is part of my school, the one I showed you a picture of the other night. Look at the south end of the re-route map. You'll see PSI Net Stadium off to the left.....a monument to "crash and burn". Kind of ironic.

Do you normally assess the health and diversity of someones carrier infrastructure by using "email bounces" as the metric ?? Your conclusions are rubbish.

I understand all the carriers have people working very hard to fix the cut, but the question which is rarely asked and even more rarely answered is where was the physical diversity in those carriers networks? Did these carriers know about this vulnerability in their network? When customers asked, were the customers told? What are MFN or Worldcom sales people telling customers who ask what happened to their network diversity? ---- The above contributed by Sean Donelan on the NANOG List. ---- As an aside (This is FAC speaking now), today I had cause to send out a bulletin to about a dozen folks across multiple orgs. Three of them were MFN types. All of the MFN emails bounced. There were no WCOM recipients on the list, so I don't know how they are weathering, although I would suspect that their ubiquity and the sheer number of routes that they have would lend to a greater likelihood of recoverability. Sean Donelan above is saying, and you seem to be agreeing, that MFN customers were down as a result of the Baltimore tunnel problem. In the MFNX Press Release first posted by Curtis Beamis in message 3388 and repeated here for convenience: biz.yahoo.com . . . This effort restores MFN's network to a fully redundant state. MFN's Internet customers experienced no service interruption due to the damage or during the repairs as IP traffic had been immediately rerouted following the incident. . . . MFN is saying that their customers did not have any outage, and that indeed they were working hard to reinstate redundancy, not service. In light of their statement, do you, or possibly Sean Donelan since I don't know how to reach him, have any other information which would call into doubt the statements from MFN?
