outside view:

from Uni-Bonn I reach apnic via

dfn fra - level3 fra/lndn01/nwrk01/asbn01/atln01/lsan01/nsyd

and Uni Auckland via

dfn fra - geant2 fra/wash - internet2 atla/hous/losa - 2401:138:2000 -
2404:138:0 - then only stars.

and U auckland via

rh-tec fra - HE fra/lon/nyc/lax - 2001:504:13 - nsw.vocusconnect - 
VOCUS syd - 2402:7800:: - brisbane.pipenetworks - 2001:dc0:2001:11::211

Something is strange with UDP filtering at UofAuck - or its upstream(s).
