According to the Associated Press, the US Defense Department took 1,500 computers offline as the result of a cyber attack. No additional information about the event was provided. Defense Secretary Robert Gates said the attack happened sometime yesterday and that e-mail systems were expected to be back online later today.

Gate said during a press conference on the matter: "We obviously have redundant systems in place. ... There will be some administrative disruptions and personal inconveniences." When asked if he, personally, had been inconvenienced, Gates replied that he's a very low tech person. "I don't do e-mail."
