Hi Justin,

Unfortunately, we only have one msync node in Australia, but not
providing IPv6 actually (I'm in contact with them and hopefully it will
change soon) so yes, your findings are correct : for all requests coming
from Oceania/Australia over IPv6, we're redirecting to the nodes in
America ...
