The problem is on Google's side. From AS15879:

Onderwerp: Re: Youtube CDN unreachable over IPv6

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.

% telnet -6 r7---sn-5hne6n7y.googlevideo.com 443
Trying 2a00:1450:401c:8::c...

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.
