Youtube CDN unreachable over IPv6
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).

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.

Is it possible for Google to realize some form of internal monitoring to catch these defunct dual stack nodes?
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.
