Youtube over IPv6 for non-whitelist users?

[Erik Kline]

Youtube is trialing the use of blacklist mode (AAAAs are served unless
the network is measured as having a high degree of brokenness) for
most of the video hostnames, rather than whitelist mode.  Folks are
watching to see how it behaves, while we continue to work on
brokenness detection and automation.

Talk ({,m}talk.google.com) are also trialing blacklist mode at the moment.

We'll see how it goes.
