There are quite a few 6to4 relays outside Europe. I think the problem  
more is that a lot of providers haven't gotten the hang of routing to  
an anycasted prefix that so many people are announcing. Or making sure  
6to4 is fast is so far down their priority list they just don't care.  
Either way, peering seems to be a lot more dense in Europe, so they're  
more likely to be peering with someone announcing a 6to4 relay there.  
Prefer sending traffic to someone you're peering with (even if it's  
further away) to someone local that you have to pay for, and you don't  
always get sensible routing on a prefix like this.

 From the best that I can tell, here's a reasonably complete list of  
who are running 6to4 relays... Its not easy to tell what country  
someone's relay is in, but this is probably close.
