netbuzz writes: "The Internet Society’s “World IPv6 Launch” is hours from lift-off and organizers are pushing a now-familiar message: "If you've been waiting to deploy IPv6, there is no reason to continue waiting," says Leslie Daigle, chief Internet technology officer with the Internet Society. "There are customers who will view your website over IPv6 now. It isn't experimental. It's out there for real." More than 50 access networks and 2,500 websites — including Google, YouTube, Facebook and Yahoo – have committed to the event by pledging to turn on support IPv6 and leave it on for good."
