June 8th 2011 is IPv6 Day.
To check your IPv6 connectivity / compatibility, visit
http://omgipv6day.com/ for a quick test and
http://test-ipv6.com/ for a more detailed test.
[edit 2010-04-24] They've changed their tests in the last few months, so on the second link, people with IPv4-only connections should get 10/10(ipv4 part) and 0/10(ipv6 part) now. Before, for fully functional IPv4-only connections, it was reading 7/10 for ipv4 which was misleading.
Because of some lingering issues with IPv6 implementations (particularly in older OSes), some major companies including Google, Facebook, and Yahoo! are going to enable IPv6 on their main website domain for one day. It will probably lose them some visitors and money, but it's needed as a wake-up call.
List of Participants
For the technically inclined, what will happen is that participating companies will be adding AAAA records for their primary websites. Right now most companies have separate subdomains which have v6 addresses (for instance, ipv6.google.com, www.ipv6.cisco.com, etc.).
