Computerworld: Hackers associated with the group Anonymous have warned that they plan to launch denial-of-service attacks on the Internet's thirteen core servers. Those servers contain the master IP address lookup lists, and a successful attack against them could affect the entire world wide web. Anonymous threatens that they will launch "Operation Global Blackout" on March 31 in order to protest against "our irresponsible leaders and the beloved bankers who are starving the world for their own selfish needs out of sheer sadistic fun."
Security experts say it's unlikely that the group could successfully take down the entire Internet. "They might affect a few of the root DNS servers, but it's unlikely they could take all of them down, at least for any period of time," wrote Robert Graham, CEO of Errata Security. "On the day of their planned Global Blackout, it's doubtful many people would notice."
