Have you used CNAME to AAAA records ? If the customers trying to access the sites used XP with SP1, there was a bug which make impossible the connection via IPv4 if IPv6 connectivity is broken. That was sorted out already by Microsoft with SP2. Otherwise ask for a traceroute6 so the trouble can be followed up. Regards, Jordi

It is possible that a broken 6to4 relay somewhere was causing problems. Running your own local 6to4 relay (rfc3068) will improve performance and reduce the chances of going through a broken one.
we have been running w/ AAAA records for production systems for the past six years w/o complaint and no 6to4 relay.
