Description

On the "ietf" SSID, IPv6 seems now down.

My Wifi interface (Ubuntu laptop):

wlp2s0    Link encap:Ethernet  HWaddr b8:08:cf:18:6f:48  
          inet addr:31.133.133.210  Bcast:31.133.143.255  Mask:255.255.240.0

mtr does not display even the first hop.

IPv4 works fine.

I have joined ietf as well, and I can ping www.ietf.org on v6. I do get a different IP from DNS, but I can ping the IP you receive as well:

Are you still seeing this problem right now? What does your routing table look like for v6?

Indeed, it now works. And I think I did nothing. Strange temporary
problem?

comment:4 Changed 13 months ago by jclarke@…

Thanks for the reply. In lieu of other data, I have to agree a strange temporary problem indeed. We are always monitoring, so we will definitely be on the look-out for other IPv6 connectivity issues. I'll go ahead and close this ticket out now, but let us know if you see any other issues.
