Did you notice any problems accessing your favorite websites last Wednesday? On Wednesday, June 8, the Internet Society coordinated World IPv6 Day, a 24-hour IPv6 "test flight." For most Internet users, June 8 was no different than any other day. There was no ticker on news programs or front page headlines stating that the Internet had melted down. In fact, there were no major issues encountered on World IPv6 Day at all, which is good news for the future of IPv6 technology.
