I think it mostly affects things the further from "backbones" that you get; a lot of ISPs took severe hits across their entire network depending on the manner in which IP space is allocated across their networks interacting with the attack patterns of Nimda. That doesn't map well to at least some usage of "edge", but I think I get your point... -george william herbert gherbert(a)retro.com

Nimda virus/worm on Sept Sept 18 and following days > 3. Multiple fiber cuts on Sept 26 I vote for #3, if you are considering a purely technological / routing Point Of View, which is the point of this mailing list. Affecting the backbones hurts everyone, everywhere, trying to do anything on the 'Net. The other are two localized (either in type or location) to matter overall. NIMDA did not affect e-mail, chat, IM, et cetera (pretty much), and did not even affect most web servers enough to matter to end users. News web sites being down did not affect anything other than the news web sites being down. And the destruction of a couple COs within a few city blocks (*and* a few city blocks :-{ ) is not - from a purely technological / routing standpoint - that big a deal. OTOH, #1 has a much more lasting impact. From increased traffic on web sites for years to come if this drags out, to the affect on "disaster planning", to the impact many of us who help run the Internet feel (I know I do), September 11th will have a much more profound impact on the 'Net than fiber cuts, especially in the long term But then, even if not one fiber was cut, not one website saw increased traffic, and not one colo was damaged on September 11th, it would still have a more of an impact than the other two in a lot of ways which are hard to measure at the command line of a cisco or Juniper. -- TTFN, patrick

ICANN wants to get into the security business

I guess it shouldn't be too surprising. After doing such a great job with domain names, ICANN wants to get involved with Internet security. http://www.icann.org/announcements/announcement-26sep01.htm Since I don't have any other plans, I may drop by to watch the fireworks.

Contrary to earlier messages suggesting that the C.O. was a complete loss, I now have it on good word that most if not all of the systems located in the West St. C.O. will be gutted and replaced. There is a massive undertaking taking place now to do just that. -FAC > > Verizon currently has not ETR for their West Street location.

Stay tuned! Somehow, I find it difficult to believe I'm dignifying this with a response (much less a public one), but here goes: Every commercial GPS unit that I have ever seen has a speed which, if exceeded, will cause the unit to shut down (usually until power-cycled). It varies from unit to unit, but in every observed case was substantially (several times) less than the speed of such weaponry in flight. Commercial units also have altitude limits, with the same consequences for exceeding them. Integrating an OEM GPS module with existing avionics systems' targeting mechanism so it can actually cause the missile to adjust its course is left as an exercise to the local defense systems integrator.

2-4 gige DWDM
by Marc Williams 27 Sep '01

27 Sep '01

Is there a cheap way of getting 2-4 gige wavelengths? (2 would do) We have some dark fiber from A to B. It would be handy to run 2-4 seperate gige connections over it without spending squids on Metro DWDM kit. -- Marc

Which had more impact on the net?
by Sean Donelan 27 Sep '01

27 Sep '01

Which had more impact on the the net? 1. Destruction in New York City Sept 11 and following days 2. Nimda virus/worm on Sept Sept 18 and following days 3. Multiple fiber cuts on Sept 26 Its not a straight forward question. They each impacted the net in different ways. The fiber cuts had the hardest, most immediate impact. It showed up as a very sharp spike in terms of packet loss and latency. But their impact was short lived. It mostly affects the backbones, and leads to lots of route flapping. The number of routes seems to go up. The Nimda, Code Red I/II, and other worms had a more difuse impact. Their effects show up with a ramping period, peaking after a few hours and then slowly declining over several days. Their impact is extremely long lived. It mostly affects the edges of the network. The destruction in NYC had an immediate impact on news web sites, but not an immediate impact on the net. Instead the failures show up as a several dips and recoveries over several hours and days after the planes impact and collapse of the towers. But outside of news sites, and beyond a 100 or so miles of NYC, the net is relatively unaffected, with a few notable exceptions of overseas networks routing through NYC facilities. Based on previous central office failures, it will take about 6 weeks for the repairs stop showing up on measurement sites.

Verizon currently has not ETR for their West Street location. We have multiple circuits that are out including a few FLM-600s and 150s in the basement of one of our locations downtown. -----Original Message----- From: Frank Coluccio [mailto:fcoluccio@dticonsulting.com] Sent: Thursday, September 27, 2001 10:04 AM To: bicknell(a)ufp.org Cc: mike(a)jungle.net; nanog(a)merit.edu Subject: Re: Re: What's really going on in Lower Manhattan fwiw, our office in the Seaport district was knocked out on 9-11 (both power and comms).

fwiw, our office in the Seaport district was knocked out on 9-11 (both power and comms). Copper from West Street was severed in the vault, and who knows what all else in the Class 5. Con Ed power was restored via street generator units last week. Yesterday, Verizon call-forwarded all of our regular POTS lines to our cellular accounts (of assorted vendors) satisfactorily, and we are now at least able to receive incomings. -FAC > > On Thu, Sep 27, 2001 at 07:38:16AM -0400, Mike Moglin wrote: > > Does anyone know what is really going on? > > *hands Mike a buck* > > *wispers: psst, pass it along* > > *whistles innocently* > > -- > Leo Bicknell - bicknell(a)ufp.org > Systems Engineer - Internetworking Engineer - CCIE 3440 > Read TMBG List - tmbg-list-request(a)tmbg.org, www.tmbg.org >
