Hello

today i discovered that my tunnel is not working,no packets incoming
i verified my setup with wireshark that the proto 41 packets are outgoing.

Same here. If it helps, traceroute is almost the same:

  3.|-- 20ge1-3.core1.prg1.he.net (91.210.16.201)                      0.0%     1   17.2  17.2  17.2  17.2   0.0
  4.|-- 100ge5-1.core1.waw1.he.net (184.105.80.146)                    0.0%     1   19.4  19.4  19.4  19.4   0.0
  5.|-- 10ge3-1.core1.ber1.he.net (184.105.213.226)                    0.0%     1   46.9  46.9  46.9  46.9   0.0
  6.|-- ???


Kindly ask about any info on it. Thanks.

The same for me.

BGP looks OK, but routing to IP 216.66.86.122 go wrong way.

Same here (Saxony, East-Germany).

sorry, actually, I'm connecting to Berlin (216.66.86.114), but that is down as well!

doktornotor

Yeah, Prague has been down since ~ Feb 20 14:30 CET as well. Verified with 3 different locations/ISPs.

P.S. And the status monitoring page is either useless, or the monitoring scripts needs a rewrite. https://tunnelbroker.net/status.php

We are currently waiting on a remote hands request to complete at the facility to restore the tunnel server(s). No ETA as of yet, but we are aware of the issue.

Thanks for info and quick response!  8)

Endpoint in Prague (216.66.86.122) is down for a while (due to HW issue) and is anchored in Berlin (216.66.86.114). Now endpoint in Berlin is down too. :/ Unluckiness...

tjeske

But they failed at the same time, the same minute. It must be related, not unluckyness. Same/related hosting company maybe? (Berlin: IPB CarrierColo Berlin; Prague: CEColo/Sitel; however, Budapest is "CE Colo", so same as Prague?, but Budapest is working).

As I understand it, the tunnel server in Prague has been down since at least Jun 20, 2016 due to a hardware issue. To avoid service interruption, they moved service in Prague (including IPv4 endpoint address) to the server in Berlin. And what happened yesterday is that the server in Berlin failed. That is why both Prague and Berlin failed at the very same moment, because they were in fact the very same server. I would call this a double failure.

Too bad that even in 2017, we are still dependent on HE.net free service to do the job, that is supposed to be provided by the ISPs that we pay.  :'(

I do have native IPv6 at home. Just at university I need the tunnel, cause I couldn't convince the IT department to switch to IPv6. They'll do it eventually, but god knows when. However, they were so kind to allow my tunnel through the firewall.

Prague-server being now at Berlin is then probably also the reason why some services mistake me being from CZ. If they take usage patterns from genuine CZ users connecting to the Prague-server in Berlin, they might appear similar to mine (also, I'm not too far from the border, in case they're using ping times and such). Bit annoying at times, if I use services that rely on the false GeoIP-database. Thanks for the info.

As for the tunnel, the people in Berlin are most likely not working a night shift to resolve this (I'm not sure how the industry works, though). So they'll respond to the request tomorrow morning, and hopefully during the day, or latest by Thursday, the tunnel will be up again.
