Tomorrow, June 8th, 2011, is World IPv6 Day and we are on track to have the website live with a IPv6 address by that time. O'kay technically it has had one for months, but no AAAA record has been in place for it. Sadly we forgot to submit our participation by the cutoff date, so we will not be listed on the dashboard for the event, but even so we expect all services to be IPv6 accessible by 00:00 June 8th.
If you aren't one of the lucky few to have native IPv6 connectivity from your ISP, and haven't setup a tunnel with a broker yet, there is still time to do so with Hurricane Electric as their approval process is nearly instant. The lab's internal network gets it's address space from them, but the outward facing site gets it's address from SixXS. If you prefer not to setup a tunnel account with a broker you can use Teredo on Windows and Miredo on pretty much anything else. They give you less control, but are designed to 'just work'.
What ever option you choose, we encourage you to join in on the event in any way you can. IPv6 has been around a while, and it's not going away. The sooner you get acquainted with it the better prepared you'll be.
