We (OCCAID) had recently turned up peering with a few networks (including HE
and others) and as a result our outbound path to HEAnet and other networks
had changed.

Some of the abrupt route changes are being corrected today evening and
hopefully should resolve pMTU problems in reaching www.ietf.org.  If you
continue to experience trouble in reaching thru OCCAID via IPv6, please
don't hesitate to drop me a line in private.
