I'm seeing very slow ipv6 traffic when downloading from mirror.fsmg.org.nz, about 300KB/s vs 23MB/s on ipv4.
I managed to contact one of the admins at fsmg.org.nz and they setup another host on WIX for me to test (different ISP) and I still get 300KB/s.
Auckland based ipv6 hosts (via APE) I can get 23MB/s, but not WIX.
Can someone from 2degrees take a look?
