No IPv6 is better than broken* IPv6.

*broken being defined as: you go to with your broken
IPv6 connection (6to4?) and fails to load within your
margin of acceptable latency, then you go to a competitor's web site.

The point of IPv6 day is that we "shake out" the issues together as
one community.  If it works great, that is great and we can make solid
decisions based on real world data on how to fix and move forward.

As an operator of a soon to be production launched IPv6-only + NAT64
service, nobody is more eager for native IPv6 content than me.  That
said, this is the right path for the content guys to dip their toes
