Dear Christopher,<br>
<br>
what is ICANN to do? Is it in its mission to be the "Defender of the
DNS"? I wonder...<br>
Perhaps ISOC could write something but from memory I can't recall
ICANN making such a statement when such incidents happened in the
past.<br>
Or perhaps it did? We could ask OCTO what's his point of view on
this.<br>
Kindest regards,<br>
<br>
Olivier<br>
