Interesting - does a v4 traceroute follow the same path? I.e. Richmond CRAN -> ibone Atlanta -> ibone Ashburn -> Pitt CRAN
Not having detailed knowledge of Comcast's network, I'd expect the Richmond CRAN has a link to the ibone in Ashburn since it's fairly close (though there may be a closer ibone location).
