Does anyone know how many conference calls will be in progress over New Year's. AT&T is providing most of the teleconference bridges for the big Y2K groups (ICC, I0PS, etc). There's something to be said for one of the few telephone companies that has experience with '00 rollovers, being incorporated in 1885. But I've also seen press on MCI Worldcom having many different conference bridges operating over New Year's. And I assume the same is true of other teleconference providers. Will this be the "mother's day" of conference bridges? How many simultaneous conference calls can the current voice bridge infrastructure support?

Silly season
by Sean Donelan 23 Dec '99

23 Dec '99

As Alan points out, it looks like silly season will be in full swing. Here is a site claiming it will check the top web sites in the world, and if 5% aren't responding at 1 minute before midnight (pick your time zone) a major disaster has happened. http://biz.yahoo.com/prnews/991222/inferno200_1.html As has been pointed out before, many sites plan to shutdown their web sites or disconnect from the Internet over the New Year's weekend. Which I guess is a self-fulling prediction. The Internet is still considered an "extra" and not a necessary connection like the telephone or ATM. I haven't heard anyone suggesting they would turn off their ATMs, even though they are Y2K ready, just to be safe. You can read ATM as representing either acronym.

> Does anyone know of a replacement for the Network Probe Daemon software = > that was distributed through the IPMA website? I've been working with colleagues at PSC on a successor called "NIMI". Its goals are: (1) accommodate a wide range of measurement policies; (2) accommodate a wide range of measurement tools; (3) take security seriously; (4) take scaling seriously. There's a paper giving an overview available from: V. Paxson, J. Mahdavi, A. Adams, and M. Mathis, An Architecture for Large-Scale Internet Measurement. IEEE Communications, Vol.36, No.8, pp 48-54, August 1998. ftp://ftp.ee.lbl.gov/papers/nimi-ieee-comm98.ps.gz The software is alpha level and under active development. The current infrastructure is 28 hosts, which we're in the process of trying to grow to double that size within the next few months. Volunteers who can host a box are highly welcomed - drop me a line at vern(a)ee.lbl.gov if interested. Vern

I've seen some amazing disasters, but I think your customer passed along an urban legend. 38 people taken to a hospital, 8 cars destroyed, coverage by television in five states; and I can't find any published reports in the newswire databases. Unless my math is very wrong, I don't understand how a 300 amp surge could damage that much stuff.

Re: Need help from UUNet's routing specialist!

We apologise for this customer-provider issue propogating to NANOG. For the information of interested folks, and to clear up any incorrect perceptions, I have copied the list on my reply. Currently, private interconnects from Teleglobe to UUnet are multiple DS-3's, in multiple cities. However, as a result of incremental load, the management and load-balancing of these is tenuous, and event-sensitive. Specifically, internal events on either network, can cause congestion as a new closest-exit path is chosen. We are currently waiting for delivery of several OC-12 circuits to replace the plethora of DS-3's. Unfortunately, provisioning OC-12's is not something many LEC's can do, let alone in a timely manner. When these are in place, the problems should go away for the forseeable future. Provisioning of additional OC-12's should be feasible in the timelines anticipated for further growth of traffic. Until then, there is some traffic engineering being done via MEDs, for the purposes of avoiding congestion. Some of this is steady-state (since certain peerin glocations are currently under-provisioned), and some is in response to congestion events. In the absence of inter-provider MPLS, to handle such things inter-provider and intra-provider outages in a semi-optimal fashion, and in the absense of excess interconnect bandwidth (to handle outage-based peak loads), there will be instances where asymmetry is required to minimize network impact of such outages. The selection of routes for application of MEDs is done on a random basis, for scalability reasons. The choice of exit modulo these MEDs is still closest exit, and will vary based on the geographic location of the end system. (The MEDs are used to de-prefer a couple of peering locations; all others operate naturally, ie closest-exit.) I hope this explanation is clear enough; if anyone has questions about this or other Teleglobe issues, please feel free to contact me directly. -- Brian Dickson, Email: briand(a)teleglobe.net Director, Backbone Engineering Tel : +1 703 755 2056 Teleglobe Communications Corp., Fax : +1 703 755 2648 Rm 3214, 11480 Commerce Park Drive, Cell : +1 703 851 9053 Reston, Virginia, USA, 20191 http://www.teleglobe.com

Internet Y2K and Europe, South America, and Middle East
by Sean Donelan 22 Dec '99

22 Dec '99

Is anyone aware of any regional joint ISP monitoring and communication efforts over New Year's for European, South American and Middle East ISPs? Or are most ISPs in those areas relying on a US-based backbone provider to keep them informed? North America, Asia, Australia/New Zealand seem to have a plethora of groups.

I don't actually think the monitoring will pick up any Y2K problems. I'm interested in the communications and monitoring to pickup all the other problems, and trying to head off rumors when something inevitably doesn't work. For example, tonight if you go to the US government's Y2K web site it's not working. It appears to be a server problem with http://www.y2k.gov/ and not a network problem. You get an error "The request did not specify a valid virtual host." I don't think its Y2K problem, and if we could contact the operators, we might find out what's wrong. If something like that happened in the early morning of January 1, without good information, rumors will spread.
