No route

[wiro]

One or two days ago I lost connection to IPv6.
I use 216.66.80.30 server and I can ping it. I can also ping my IPv6 adress and IP6 adress of tunnel server.
When I try to ping other hosts I give:
From wiro.tunnel.tserv6.fra1.ipv6.he.net icmp_seq=1 Destination unreachable: No route

My routes are:
2001:470:1f0a:20a::/64 via :: dev he-ipv6  metric 256  expires 17181518sec mtu 1480 advmss 1420 hoplimit 4294967295

default dev he-ipv6  metric 1024  expires 21333876sec mtu 1480 advmss 1420 hoplimit 4294967295

Any idea ?

One or two days ago I lost connection to IPv6.
I use 216.66.80.30 server and I can ping it. I can also ping my IPv6 adress and IP6 adress of tunnel server.
From wiro.tunnel.tserv6.fra1.ipv6.he.net icmp_seq=1 Destination unreachable: No route
Any idea ?

I am also connected to the FRA tunnel and also had problems. Today in the morning tserv6.fra1.ipv6.he.net was not reachable via ipv4 and now it is so they are probably working on it.

I have just checked and for eg tserv10.par1.ipv6.he.net, tserv5.lon1.ipv6.he.net, tserv9.chi1.ipv6.he.net, are also affected.
So they have a lot of work.

It looks like HE internal ipv6 routing is having a problem all over the world.

The German tunnel-server required some work and is back up now.

I'm not seeing any other IPv6 routing issues going on "all over the world", or with the other tunnel servers you listed.

If you can report the problems you see to ipv6@he.net so we can track in our ticket system, that would be most helpful.

Thanks!

I might have misunderstude the results of the traceroute like this one:

Agreed, that is odd behavior for the loopback address on both tunnel-servers. I'll fiddle around and see why that isn't happy. BGP between the tunnel-servers and core routers is operational though, so tunnel traffic won't be affected by any issues with the loopback addresses.

Agreed, that is odd behavior for the loopback address on both tunnel-servers.

Probably all of the tunnel-servers have the same unreachablity.
Eg. traceroute6 tserv8.dal1.ipv6.he.net

BGP between the tunnel-servers and core routers is operational though, so tunnel traffic won't be affected by any issues with the loopback addresses.

I haven't figuered any other way of seeing if this is only tserv6.fra1.ipv6.he.net unavailable or otheres then by tracerouting (loopback) adresses.
So that was worrying that they all routed to SJC. My apologise for my comment about "all over the world".

Cheers.
