 For example, the first traceroute originating in Chicago, and if the
 hostnames are anything to go by:

 Chicago - Dallas - Atlanta - Miama - NYC - Amsterdam -
 Frankfurt - France - D.C. - Atlanta...

 The first 2 traceroutes are on SixXs tunnels and the third is native.

David,

We see what's going on.  It currently affects only a portion of the v6
