Hello,
in den last days I had a bad performance on my IPv6 connection, but my IPv4 connection works just fine. I did take the time today to do some traceroutes and pings. My DSL provider is Deutsche Telekom in Germany and I am using the Tunnel server 216.66.80.30 in Frankfurt.
Here is a traceroute:

If I ping 216.66.80.30 there is a lost of ~20%:
Ping-Statistik für 216.66.80.30:

(20% Verlust),
Ca. Zeitangaben in Millisek.:
Minimum = 37ms, Maximum = 479ms, Mittelwert = 76ms
Translated: 513 packets sent, 407 received, lost 106 - Times: min 37ms, max 479ms, avg. 76ms
I also did the same ping to the Server 216.66.86.143 in Berlin that also has the same 20% lost pings.
The ping to the last hop with the IP 184.105.65.118 has no lost pings an quite stable ping times at ~40ms with only small variations so I thing that the problems are between 184.105.65.118 and 216.66.80.30.
I did verify the ping from another DSL line that is connected to Vodafone Germany, but that shows the same ping loss so I rule out problems with my DSL provider Deutsche Telekom.
Are there any known issues with the german tunnel servers?
Frankfurt tunnels were migrated to Berlin temporarily while it gets a hardware replacement. Berlin also started suffering some load and loss, but we've done a little tuning and it should be looking better.
Yes, looks much better now. No ping losses anymore and no hanging on my SSH connections. Thank you for the information. :)
could this https://forums.he.net/index.php?topic=3778.0 (https://forums.he.net/index.php?topic=3778.0) kind of Problem be related?
I continue having severe problems with HE tunnels. I was using FRA1 from M-net and the IPv6 connection, specifically SSH, would freeze every 10–15 seconds for a couple seconds each time.
I thought this might have been related to the hardware issues at FRA1, so I tried other tunnels, specifically BER1, but the problems remain the same.
Is this a load issue with the tunnels, or a peering problem with M-net?
