Traffic not passing and router unreachable
![[gb]](/s/countries/gb.gif) Shadow Hawkins on Thursday, 22 January 2009 19:47:14
I have read and followed the "Reporting Problems" section on the Contact page and am providing the following details for this report based on the list of items stated there:
Since 0700 2009-01-22 traffic has ceased flowing from my ayiya tunnel to dkcph01. At around 1930 I was able to re-establish the tunnel, but traffic is still not flowing, nor can I ping the pop router address through my other working tunnel. Please see the following diagnostic information:-

The same problem is occurring today, starting 10:33:38 CEST. Since noosl01 is down, now I have no IPv6 connectivity at all.

Please actually read the "Reporting Problems" section on the Contact page and provide the details requested there.
"It does not work" and later "Now it does work" kind of statements don't really help at all.
