Ticket ID: SIXXS #13420489 Ticket Status: Remote Problem PoP: deham02 - Easynet (Hamburg)
Some IPv6 sites are no more reachable via SiXXS-tunnel
![[de]](/s/countries/de.gif) Shadow Hawkins on Tuesday, 31 March 2015 19:36:11
Dear SiXXS staff, dear ISP staff,
since yesterday I have partial connectivity problems with my deham02 tunnel; some pages are reachable as usual (e.g. ipv6.he.net), others not. I re-checked my (unchanged) configuration and attempted to reconnect, but still I can't get usual IPv6 routing. Could you please check whether there is a problem with the deham02 pop?
Thanks in advance and kind regards,
Nicolas

Dear staff,
I got the same problem, only difference: I am on the deham01 pop.
To check if it could be the same issue, I ran the same traceroutes as Nicolas did (output below).
I don't have any problems if I try the same from my servers at different locations.
Thank you in advance and best regards,
Bernhard

Some IPv6 sites are no more reachable via SiXXS-tunnel
Shadow Hawkins on Wednesday, 01 April 2015 05:38:06
For what it's worth, I'm on deham01 and I started noticing this very problem on March 20, when www.google.com and en.wikipedia.org became unreachable over IPv6. (My traceroutes look the same as those already posted.)

Hi,
have a look at SIXXS #13414977, I think this is the same issue.
Regards,
Andreas

We are unable to resolve routing problems in remote networks.

The remote routing problem seems to be solved. Thanks to everybody being involved!
