DNS Trouble Knocks NSA Off Internet

Robert McMillan writes on InfoWorld.com:

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 problem was resolved at around 11 a.m. Pacific time, according to Web site measurement company Netcraft.

The Web site was unreachable because of a problem with the NSA's DNS 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.

The agency's two authoritative DNS servers were unreachable Thursday morning, McPherson said.
