After some poking around with traceroute: Looks like it's directly connected
to darenet.dk, and going through nordu.net to get there, and it looks like
nordu.net's main connectivity <http://www.nordu.net/connectivity/> to the US
is through a tangled mess of ebone.net (8 hops in that backbone alone). And
that's not even mentioning anything you have to go through in the US, which
could be a lot if you're, say, on a cable modem on the west coast.
Solution: Darenet needs to get more and better interconnects, and maybe
optimize their own network a bit (7 hops there is quite a few). And there
need to be more transatlantic links overall.
Luckily at work, we peer directly with nordu.net's academic-only link to
Abilene. :)
