Title: Tunnels over frankfurt server down?
Post by: kart0ffelsack on May 13, 2013, 07:04:07 AM
Hi since this noon tunnels over the frankfurt server don't seem to work anymore. I tried it with my main tunnel and a new one i created for testing from several hosts but all tests had the same result.

A traceroute from inside the tunnel looks like this:
traceroute to heise.de (2a02:2e0:3fe:100::8) from 2001:470:1f0b:196::5eed, 30 hops max, 24 byte packets
1  [username].tunnel.tserv6.fra1.ipv6.he.net (2001:470:1f0a:196::1)  12.962 ms  7.693 ms  7.852 ms
2  * * *
3  * * *
4  * * *
5  * * *
[...]

and from another ipv6 host outside the tunnel the traceroute looks like this:

traceroute to 2001:470:1f0b:196::deed (2001:470:1f0b:196::deed), 30 hops max, 80 byte packets

To me it looks like someone/something messed up the routing on/to that server.

Same here, using tserv1.fra1.he.net. I can still ping the tunnel server, but nothing seems to go through the tunnel.

I think the problems began sometime around 11:00 CEST.

I can also confirm this problem, no packets can be transmitted via tserv1 in Frankfurt.

Somewhere between 11:50 and 11:55 CEST according to my smokeping stats.

It is up again.

It is down again. This time the symptoms are different. IPv4 packets cannot be delivered to the tunnel server. But some of the IPv6 packets send to the tunnel server are delivered over the tunnel. I have opened ticket #2171493 about this issue.

The ping6 -n google.com command I have had running for 9½ minutes just responded. And I actually got all 585 echo replies back, the first one arrived with a 573095 ms roundtrip time.
