For .ZA, I've only really seen native IPv6 at jupiter.is and on the TEnet (NREN) network. My university campus doesn't even have native IPv6 available for servers I maintain.

From what I've seen running an HE tunnel through London, Youtube and Facebook make up the bulk of IPv6 traffic (as expected). At least those networks are the only thing routinely dedicating 10%+ of the total inbound traffic to IPv6 according to my home network flow analysis (I think it's about 18% IPv6 usage on a monthly basis).
