Recently, my routed /48 appears to have stopped working. I am on tserv5.
I can access the internet from my client endpoint address and from addresses in my routed /64, but not from addresses in my routed /48.
As far as I know, I did not make any configuration change that triggered this, and I have tried assigning an address from each range to my tunnel endpoint and pinging straight from there to the server endpoint address:
# ping6 -c 1 -I 2001:470:1f08:907::2 2001:470:1f08:907::1
PING 2001:470:1f08:907::1(2001:470:1f08:907::1) from 2001:470:1f08:907::2 : 56 data bytes
64 bytes from 2001:470:1f08:907::1: icmp_seq=1 ttl=64 time=1.34 ms
# ping6 -c 1 -I 2001:470:1f09:907::9 2001:470:1f08:907::1
PING 2001:470:1f08:907::1(2001:470:1f08:907::1) from 2001:470:1f09:907::9 : 56 data bytes
64 bytes from 2001:470:1f08:907::1: icmp_seq=1 ttl=64 time=1.36 ms
# ping6 -c 1 -I 2001:470:9559::9 2001:470:1f08:907::1
PING 2001:470:1f08:907::1(2001:470:1f08:907::1) from 2001:470:9559::9 : 56 data bytes
(No response)
Is this likely to be a problem with the tunnel server, or does anyone have any suggestions about configuration to check at my end?
Same here - working fine until some time after 4pm BST today (16th August).
Can ping tserv5.lon1.ipv6.he.net (216.66.80.26), and seeing outgoing packets with proto 41, but no responses.
Local IPV4 address hasn't changed. Re-established tunnel and still have same problem.
Tunnels are rebuilding and verified that they are correct. Once that finishes, then the /48s get configured.
Thanks, working ok again now.
(First outage I've noticed in over 6 months - top service :)

Would this explain why my tunnel stopped working about 15 minutes ago?

Either way, seems to jam on HE's network on the west coast.
Last I checked Seattle isn't either London, or in the UK ;)
Either provide the destination that failed in that MTR, or email ipv6@he.net to open a ticket so we can troubleshoot it outside of someone's London thread.

Thanks for the quick response. I'll send an email. FYI the destination of the second tracepath was zoth-ommog.unzane.com which is on my tunnel - gturner-1.tunnel.tserv14.sea1.ipv6.he.net. And sorry for hijacking a London thread =)

Nevermind, it's back up.
