I'm guessing the Flash player is doing some quick connectivity checks and serving over IPv6 if available. Anyone else seeing this? Has Google publicly stated that they're doing this? Is it new since v6 day?

It gives Google a higher volume of IPv6 performance/connectivity intelligence too, which is surely good :)   Facebook left their developers.facebook.com site on v6 too, as did MS with www.xbox.com, so it seems the bigger players are leaving more content up to get more measurements/experience.

FWIW, put us on the list too - Cisco kept AAAAs on www.scansafe.com
