Last month's World IPv6 Day created some excitement about IPv6. Once it was over, however, everyone went back to work—which for most people doesn't include anything IPv6-related.
The idea behind World IPv6 Day on the 8th of June was to flush out broken IPv6 setups by simultaneously turning on IPv6 across a large number of Web properties—including the four largest in the world. Few, if any, problems were reported, so in that sense WIPv6D was a resounding success. Apparently, it's possible to add IPv6 addresses to large Web destinations without significant adverse effects.
