Why do you insist that the ability to traceroute to it is an operational requirement? Same machine for both tld1 and tld2, seen through XO last night and Verio this morning, from source prefix 66.56.64.0/19 (as well as two others, one on the US east coast and one in US midwest which I cannot name publicly). Judging from the bulk of monitoring data available, the problem you were experiencing possibly had a slightly smaller scope. You do realize your diagnosis is analagous to the dialup ISP user calling his helpdesk and claiming "the internet is down," right? So as far as my machine's source address is concerned, even if the servers are anycast, there are still only two servers which reside on a single point of failure. Anycasting doesn't help me one whit if there are only two servers for my named to choose and both of the ones visible from my location are down (even though their routes are up) -- this is IMNSHO irresponsible for a gTLD operator. An IP is just a destination. In this case it likely refers to a cluster of machines. Would you be happier if each machine in the cluster had its own .org delegation? That could probably be shown to be a pretty sub-optimal solution. If you're still confused, have a read here: http://www.ultradns.com/support/managed_dns_faq.cfm "Q. I read that your service is supposed to make use of several servers all over the world, but you only give users two server addresses to provide to their registrar. How do I make use of all the other servers?" If that doesn't clear things up for you, you might want to take a look at this: http://www.amazon.com/exec/obidos/ASIN/0764516779/ HTH, HAND. matto --mghali () snark net------------------------------------------<darwin>< Flowers on the razor wire/I know you're here/We are few/And far between/I was thinking about her skin/Love is a many splintered thing/Don't be afraid now/Just walk on in. #include <disclaim.h>
