I have noticed problems with reachability of the http://www.mikrotik.com web site over the IPv6 connectivity. DNS query for http://www.mikrotik.com returns AAAA record without any problem. But the target network is not reachable. I did some tests from two independent locations with native IPv6 connectivity with no luck.
