Hello,
I have a SIXXS ipv6 tunnel that terminates in Ashburn, Va.
I have two HE ipv6 tunnels, one terminates in Dallas the other
terminate in Ashburn. I can ping each endpoint of the tunnels that terminate
in Ashburn, but I can't ping between the SIXXS and HE with the HE termination in Dallas.
Using Looking Glass at HE I can traceroute to my SIXXS tunnel from Chicago but
not from Dallas.
Any ideas on how to get this fixed.
This problem only started occurring within the last week or so.
Thanks for your indulgence,
Contact the providers involved directly?
Sending a mail to ipv6@he.net + info@sixxs.net should get you what you
need, given that you actually provide IP addresses and other such useful
diagnostics like interface configuration, routing tables etc etc etc.
The above mail is far from useful and nobody would be able to help you
in anyway except to state the above.
Greets,
Jeroen
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.

I did and now it appears to be resolved. Thanks HE and SixXS.
noc@he.net have always been good when I've had strange issues.
It wasn't strictly an HE problem, since I could reproduce it from Level3's looking glass. In both cases, the occaid.net router in Atlanta appeared to be the Point of Breakage.
It looks like the problem has been resolved.
