most news TV are making it sound like a hacker has taken down PSN and Xbox when its a DDoS that has taken it down (and they also fail to say that very likely Kim D likey stopped it after offering them free mega accounts but i guess the public facing news site may have a gag order not to disclose this information)
there are lots of ways of mitigating attacks like this but who knows if they would do it as it cost money and bandwidth
