More than 550,000 domains are registered with Joker, meaning the outages could be widely felt. It's not clear why the DDoS is succeeding, as most registrars have implemented sturdy DDoS protection since the attack on the root nameserver system back in 2002.' Some security experts have warned in recent weeks about DNS recursion attacks as previously discussed here on Slashdot, which can amplify the power of attacks launched from botnets."
