In the last few weeks I noticed that many users, usually from the US,
reported the same kind of problems.
I think that having more public 6to4 relays is a good thing, even if
announced only at the local IXes.

In the RIPE region, we share access to the related IRR objects.
Having some documentation to help new sites setting up relays would
probably be useful too, many large backbones have IPv6 connectivity but
do not announce the IPv4 anycast prefix even to their customers
(possibly because of DoS concerns).
