Tokyo tunnel server routing

Hello,

As we can see on http://www.tunnelbroker.net/usage/tunnels_by_latency.php, only about 19 tunnels on the Tokyo tunnel server have ping less than 100 msec (the 20th tunnel in the top list has 108ms).

The traceroutes look like this:

Code:

Host Loss% Snt Last Avg Best Wrst StDev
1. cloud1.japan.so.cm 0.0% 11 0.0 0.1 0.0 0.1 0.0
2. ge3-42.ar1.tko1.jp.scnet.net 0.0% 10 11.1 6.8 0.4 53.9 16.9
3. xe-0-0-0.cr1.tko1.jp.scnet.net 0.0% 10 0.3 2.0 0.3 17.0 5.3
4. ???
5. tserv1.tyo1.he.net 0.0% 10 120.1 120.2 120.1 120.2 0.0

Code:

15 117 ms 117 ms 117 ms cloud1.japan.so.cm (50.31.254.105)

So it first goes to San Jose in the US for the outbond transfer from core1.tyo1.he.net, and presumably from the tunnel server too. It's not just to my particular network, according to http://tunnelbroker.net/usage/tunnels_by_tserv.php there are 1490 tunnels on the Tokyo tunnel server, and judging from the top latency list, 1471 of them are affected by this issue and have ping higher than 100 msec to the tunnel server. Can you please look into fixing this situation?

Thanks

Yes, this is a problem! The latency from a location in Japan (close to Osaka) to Tokyo is 250ms right now... Traffic gets routed over the US. Is there any plan to fix this soon? If not it would be better to change the endpoint to somewhere in the US...

Here is my traceroute:

This sounds like something you should open a ticket with ipv6@he.net to get resolved.

Sounds like you should contact your ISP and get them or their upstreams to peer with HE in JPIX or JPNAP.
