Google recently enabled IPv6 support for their popular video portal YouTube. This resulted in a significant increase of IPv6 traffic on the Internet. The amount of IPv6 traffic running through the DE-CIX e.g. grew roughly by a factor of four.
This is a big step in the right direction in my opinion. Finally a lot of popular content is made available to end users via IPv6. Thanks a lot Google!
I only wish they would admit more Internet Service Providers to the Google over IPv6 project. My ISP AAISP still cannot get access although they are among the few which offer native IPv6 connectivity to their customers. 🙁
