A denial-of-service attack apparently overwhelmed two of the thirteen root domain name servers early Tuesday morning, according to data collected by Internet infrastructure service RIPE NCC.
The attack caused the G and L servers to fail to respond to at least 90 percent of queries, according to the RIPE data. Two other root servers also appeared to have suffered from dropped traffic, and the Associated Press reported that a third server had been overwhelmed by the attack.
In 2002, a similar attack struck the thirteen domain name servers and seriously disrupted at least eight of the systems. Even that attack, however, failed to affect most Internet users, although it underscored that reliability and security were still problems for individual root servers. Last year, massive attacks on domain name servers took anti-spam service Blue Security off the Internet and eventually caused the business to cease its fight against spammers.
No one company or organization controls the thirteen servers. The two affected servers are managed by the Internet Corporation for Assigned Names and Numbers and the U.S. Department of Defense.
