Hello --
I use Hurricane Electric IPv6 Tunnel that is working just fine. When I try to load frontier.com, however, the connection resets. I can ping it fine, though, which goes through the IPv6 tunnel.
What's odd is that I can't load just the front page -- other pages load okay.
Any idea?
C:\Windows\system32>tracert frontier.com

On either native Comcast or HE colo, I get the following with curl:
:~$ curl -6 http://www.frontier.com -v

and this is what I see with tracepath6:

Hmmm, I get the same thing with curl.
It works if I turn the tunnel off, though.
It works with the tunnel in LA.
Definitely seeing some weirdness but I think its on frontier's end... From my HE.net tunnel traceroute6 behaves weird looping through two hops:
