Hello Jimmy,
I'm still seeing this behavior, which is causing a good amount of
Teredo-based connectivity to fail. The relay appears to be
miredo.surfnet.nl - any chance someone on the list is from SURFNet and
could take a look?
If you can send me offlist some traces i can check for you.
This path for 2001::/32 leads to a broken teredo relay:
3257 1103 1101
http://ip6.me was using this path and not working from my client. When I
routing to prefer 6939's relays it started working.
We see ~ 180 mbps running over the relay so i doubt its a generic thing.
Bye,
Raymond.
