few sensors so we cannot be sure if it was a DNS poisoning or an
illegal access to the DNS hoster (I say DNS hoster because the NS have
not been changed, as they would have been during an attack at the
registry or registrar) Web interface.
For the NS, the only change was the withdrawal of ans1.kanartel.sd and
ans2.kanartel.sd from the set (they were in the zone but never at the
parent) around 2014-12-18 04:30:00, after the attack.
For the A:
