DNS Trouble Knocks NSA off Internet
A server problem at the U.S. National Security Agency has knocked the secretive intelligence agency off the Internet.
The nsa.gov Web site was unresponsive at 7 a.m. Pacific time Thursday and continued to be unavailable throughout the morning for Internet users.
The Web site was unreachable because of a problem with the NSA's DNS (Domain Name System) servers, said Danny McPherson, chief research officer with Arbor Networks. DNS servers are used to translate things like the Web addresses typed into machine-readable Internet Protocol addresses that computers use to find each other on the Internet.
