It was last spring/summer. You can find it also in the archive of this 
list.

In short:

xbox did not work at several (IPv6) providers. Some of them have patched 
their routers and found a solution with Microsoft (comcast).
In other parts of the world, *the solution* was to allow teredo at an 
IPv6-Access.
Because I don't own a xbox I haven't sniffed the network behaviour, but 
I observe some costumer portals (e.g. Kabel Deutschland/Vodafone) and 
there are still problems, often related to IPv6. (can have other reasons 
too, like instability at all, Firewalls or something else)
