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.

It seems that 50% of the times customers complain they have > a poor connection to our network, it turns out that they're going via > teleglobe at some point! Um, maybe it has to do with your connection to the outside world? (BTW, are you refering to pre.org, specifically, or some other network?) Or at least connectivity between your upstream provider and either you or us... Currently we hear your routes only from insnet, via LINX and DE-CIX. (LINX does tend to have problems from time to time.) The proportion of complaints coming from customers of ours is most likely explained by the size of our customer base; a recent check on percentage of announced IPv4 space, shows us and our customers comprising about 20% of reachable addresses (ie, pro-rated by prefix size). > Are they running a 2400baud modem with a flaky fuse as their main > connection or something? Try multiple OC-12 (cross-section), with buildout to OC-48 (on dark fibre) underway, in North America and Europe, and deployment of significant numbers of nodes worldwide at significant connection speeds, over owned wet-fibre and dark-fibre capacity. We do have lots of *customers* whose links to us are congested; if anyone can find a way to force customers to upgrade, we'd dearly like to know. ;-) (These congested links have in-addr entries from our namespace, and this frequently leads to the incorrect conclusion that it is our network that has problems. In case anyone is curious, our naming convention for point to point links, is if-* for the Teleglobe end, and ix-* for the customer side, where the * is the numbering of Cisco interfaces converted from non-alpha to hyphens, in the zone named by the router designation. Example: if-12-1.bb3.NewYork.Teleglobe.net, would be the Teleglobe side, while ix-0-1-0.bb6.NewYork.Teleglobe.net would be the far-end of a link.) -- 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

ORBS block
by Dean Anderson 18 Dec '99

18 Dec '99

Well, after almost a month of no attacks and a coincident month of ORBS blocking at BBN/NZ link, the block on ORBS has been lifted, and we have started getting relay attacks again. I think thats pretty conclusive evidence that they are the cause of the relay attacks. I'm hoping the removal was an oversight, but I'd like to ask people to please put the following access lists in: access-list 104 deny ip 202.36.148.5 0.0.0.255 any access-list 104 deny ip 202.36.147.16 0.0.0.255 any Luckily, the FBI just called me back to begin work on last months attacks. I guess Egypt Air must be getting wrapped up. I guess I have some stuff to add to our complaints. Actually, given the cause and effect demonstrated by the block, I'm hoping that this will motivate the FBI to do something with ORBS. --Dean ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Plain Aviation, Inc dean(a)av8.com LAN/WAN/UNIX/NT/TCPIP http://www.av8.com ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

I haven't heard any announcements of other ccTLD registrars closing down for the holidays. However, its is not unusual for operators of some ccTLDs and the sub-US domains to dissappear for days or weeks over holidays. Try to get a hold of sub-US domain registrars during the entire month of August in the US.

NZ ccTLD registry closing down for Christmas!
by Joe Abley 18 Dec '99

18 Dec '99

For the (probably few) operators who are in the business of registering and parking names under the NZ (New Zealand) ccTLD, we have just been notified that the NZ registry, Domainz, is closing down for Christmas -- no modifications to the zone files until 6 January. Does anybody know of _any_ other TLD registry that is closing down for Christmas? I'd be interested to hear, if so.
