Youtube CDN unreachable over IPv6

Fri Nov 6 18:17:48 UTC 2015

Hi all,

Thanks for the reports.

To the best of our knowledge, this issue has been resolved at this
time. If you are still having problems connecting to YouTube CDN
nodes, please feel free to let me know, and I will investigate
further.

Blair,

I'm not aware of a similar issue with IPv6 being unavailable while
IPv4 is available recently.

I did not see any threads with information in them with the name
"Blair" attached in either the October archive
(http://mailman.nanog.org/pipermail/nanog/2015-October/thread.html) or
the September archive
(http://mailman.nanog.org/pipermail/nanog/2015-September/thread.html)
.

If this issue is ongoing, I would be happy to look into this;
otherwise, I don't believe there is any action I can take to assist at
this time.

All the best.
