It's being called one of the most significant attacks on the Internet in years. Experts say hackers briefly overwhelmed at least three of the 13 computers that help manage global computer traffic Tuesday.
The attacks went on for hours, but for the most part didn't get in the way of most computer users. Behind the scenes, though, computer scientists have been scrambling to cope with enormous volumes of data that threaten to clog up some of the Internet's most vital pipelines.
Experts say the hackers involved in the attacks may have tried to cover up their origins, but much of the rogue data has been traced to South Korea.
The targeted servers included ones operated by the Pentagon and the Internet's primary oversight body.
