    I'm not positive that this is still the case, but I believe that
there can be quite a bit of latency in mirroring due to the
way RIPE database code (which ARIN uses) works.   The
last object(s) registered are not pushed to the mirror stream until
the next object(s) are registered.    I believe RIPE regularly pushes
a dummy object in order to keep it's mirrors more regularly
synced.   I don't think that ARIN does this.   It's a bigger issue
for ARIN as their routing registry is updated less frequently
than the RIPE routing registry.

   According to our logs, the objects were not mirrored on
the RADB server until about 2.5 hours after Tomoya posted
his email (the objects were picked up from the ARIN
mirror at 05:37:42 -0500 (EST)  March 2).
