This year's IPv6 day (or IPv6 Launch Day) was not just testing (see 2011 report here) but for real: "Major Internet service providers (ISPs), home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services by 6 June 2012".
Don Bowman from Sandvine provides some statistics on this D Day - "Looking at the preliminary data, this year’s World IPv6 Day was not simply turned on with one big flick of a switch, instead it looks as though yesterday’s date simply served as a deadline that many websites have been working towards over the past year to meet".
Cam Cullen from Procera Networks shows similar findings: " The growth in “normal” IPv6 traffic started to ramp in April, with more users taking advantage of native IPv6 services being offered by this operator, as well as the content providers, most notably YouTube, as shown below, but with Facebook and Amazon making an appearance"
Darren Anstee from Arbor Networks saw a "..doubling of the amount of IPv6 traffic tracked by the ATLAS system during the day, which represented a change from approximately 0.012% of internet traffic to 0.024% of internet traffic .. things are moving forward over the past year with the amount of IPv6 traffic we are tracking having increased substantially. IPv6 now peaks at around 0.1%".

According to Sandvine - ".. YouTube accounted for more than half of all Native IPv6 traffic, while Facebook (fbcdn.net and facebook.com) leapt up the list. Some notable domains that tumbled down the rankings (or disappeared entirely) include: edgesuite.net, llnwd.net (Limelight), apple.com, playstation.net, hbogo.com, and pandora.com"
