Before that they used our (Tele2) 6to4 relays in Amsterdam and Paris. I 
think this was discussed here 1-2 years back.

I couldn't find it, but

says the same thing.

I urge more people to look up what 6to4 relays you're using and set up 
your own if needed. People *are* using it and you not doing it is making 
things worse for your customers. Yes, 6to4 is generally bad but it's out 
there. Everybody needs to think about it.
