8th June 2011 is the kick-off date, leading content providers will turn on IPv6 and keep it on.
IPv6 day broke the chicken and egg problem, and it provided a target date for some of the deployments.
Practically no problems happened, which is terrific, but overall traffic was low.
6th June 2012: IPv6 will become part of regular business on by default.
This time, access networks will also be involved. (www.worldipv6launch.org)
New subscribers get IPv6 by default after 6.6. 2012.
