Dear Google,
It appears that one of the Youtube CDN's (in Europe, NL) is not
reachable over IPv6 from AS 20844. Can someone get back to us on this,
the company can't access any of the videos currently, although the
mainpage loads fine (over IPv6).
Kind regards,
Seth

It's not just you, I'm seeing the same thing from my home connection in AS3265. I think this started happening not long ago when Google had an issue with one of their AMS-IX connections.

I'm certain it's not AS3265 who is to blame here, an ISP I've had pretty much zero issues with over, IPv6 or otherwise, the many years I've been a customer.

This was happening two weeks ago in the Bay Area as well. It happens quite
a lot, actually...search for my old threads. I gave up trying to get it
noticed.
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.
It was 2014-05-17 on this list, and went on to be handled at GGC, where
it's come up now and then.

Is it possible for Google to realize some form of internal monitoring to
catch these defunct dual stack nodes?
Kind regards,
Seth
A traceroute to both would help greatly in determining whether it's really
Google's fault, or if your ipv6 routing is borked.
I can reach the rest of the Google IPv6 services over IPv6, the player
loads, but the video stream does not.
I've pasted the traceroute below.
