US security agency stumped by internet outage

2008/05/16

The website of the US National Security Agency (NSA) is currently feeling the effects of an internet outage, often avoided with the use of website monitoring services, which surfaced yesterday (Thursday, May 15th).

According to reports, the NSA's address was unresponsive for a period of four hours during the morning after a problem with the organisation's Domain Name System (DNS) servers.

Arbor Networks' chief research officer Danny McPherson explained to PC World: "It's either an internal routing problem of some sort on their side or they've messed up some firewall or ACL [access control list] policy.

"Or they've taken their servers off-line because something happened."

The NSA, which conducts specialised activities to protect US government information systems, suffered a previous outage in 2000.

A failure of an aging communications structure due to a software anomaly was remedied at a cost of $1.5 million (£750,000).
