A sophisticated distributed denial-of-service (DDoS) blocked Dutch government and privately run commercial sites from the public for more than 10 hours Tuesday. Blog site Geenstijl.nl and telecom provider Telfort’s site were among those blocked in the attack. The attack was different from the usual DDoS attempts that happen on an almost daily basis and are easier to defend against, Prolocation’s Raymond Dijkxhoorn said. The Dutch government did not use external DDoS protection services, he said.”]
