This looks like it is a bottleneck across the pond..  I'm seeing the
same bottleneck when I trace back via a different site on Internet2.

Last I knew, GEANT had multiple 10 gige to new york (via the
Netherlands), and that is where it peers Abilene.  The link is not
saturated by any means[1], and GEANT looks to be fine as well[2].  If
the problem persists I can talk to some people in Abilene on Monday.
Most of them are still at the SC04 conference tearing down the network
there this weekend.

Cheers,
