World IPv6 Day Has Started
June 8th 2011 (00:00 - 23:59 GMT) is World IPv6 day, when a number of large internet organisations such as Google, Facebook et al are enabling IPv6 for the next 24 hours. With widespread testing tools available ahead of the event, the expectation is that few users, if any, should experience connectivity problems today.

With the final IPv4 blocks having already been allocated, moving over to IPv6 is an essential step in the continuation of the internet's growth throughout the globe. But like the chicken-and-egg scenario, without IPv6 hosts to visit, there seems little advantage in clients having IPv6 connectivity.
The tide is turning though, with many Asian countries aggressively rolling out IPv6 servers and clients. If World IPv6 day is a success, then it may well be that the servers keep the IPv6 enabled from now onwards.
