Actually, I was about to send a message about this.  I believe the 
problem is in occaid.net, particularly their router in Atlanta.

SIXXS uses a variety of providers at various PoPs to provide their 
tunnel connectivity and occaid.net is the provider at Ashburn (I have a 
SIXXS tunnel there as well).  Tracerouting from the West Coast or Texas 
goes through occaid.net's router in Atlanta and dies there with 'network 
unreachable':

Tracerouting from the East Coast is fine:

Attempts to get a response from noc () occaid net regarding this issue over 
the past 36 hours have failed.  If there is anyone here from occaid.net 
or knows a clueful person there, can you please point them to this thread.

I still think it's a good idea to contact info () sixxs net, so they know 
what's going on, but I don't think it's actually their problem.
