And the list goes on and on, for instance due to OS weirdness (or shall I say brokenness) probably half of the traffic I could get over IPv6 comes in over IPv4, this solely relies on whatever DNS query returns first. Accoording to reports on nanog, DECNIC just stopped responding to queries from 6to4 hosts, this might show a drop again in the German graphs.
Would that be "DENIC"? If yes, can you point me to the Nanog article?
Yeah, sorry for the typo:

Mmmh. To clarify: this is not "DENIC not responding to DNS queries (packets) from 6to4 addresses" but this is "DENIC refusing to delegate a new .de domain to nameservers that have (only) 6to4 connectivity". DENIC does DNS checks before delegating a zone.de, and their rules are numerous and amazing... But in *this* case, I'm not going to argue the case - the usefulness of 6to4 connectivity for a name server is something which you can spend debating hours and hours, and people will still disagree :-)
(Since we're providing IPv6 transit to DENIC, it might be a problem with our 6to4 relay - or with their routing. They're multihomed, they make their own mistakes^Wdecisions...)
Love to hear if in fact this is policy or simply a technical issue and bad translation from a service representative.
It's policy, and it's not a technical issue. So as a transport provider, there is nothing we can do about it.
