Internet speeds in the world, especially in parts of continental Europe, reportedly slowed. It is not caused by damage to infrastructure or the existing submarine cable exposed anchors, as happened to one of the internet network operator Indonesia some time ago.
Slowing the internet in Europe is caused by a distributed denial of service attack (DDoS) is claimed to be the largest in history.
Typically, to launch DDoS attacks, the attacker exploit server or botnet to send fake traffic to the target with the hope of making the target server to be offline or dead.
However, the attack was allegedly a little different this time. Hacker allegedly used a problem in the Domain Name System (DNS) servers to bombard the victim with internet traffic from all over the world. The scale of the attack is known as the largest in history for being able to reach 300 GB per second.
DDoS attack is redirected to a network security company called Spamhaus. The company is headquartered in the city of Geneva (Switzerland) and London (UK) has been working to make the black list (blacklist) web sites that are considered dangerous.
The black list will be sold to various companies internet service provider (ISP) that typically use this list as a reference to block web sites that are considered dangerous.
As quoted from Mashable, Thursday (03/28/2013), the black list is expected to "be responsible" for blocking 80 percent of spam e-mails around the world.
Spamhaus itself is rumored to be a victim of a DDoS attack after adding Cyberbunker, a Dutch internet organizers, the black list.
Cyberbunker is a data storage service that allows users to store all data, except for child pornography and matters relating to terrorism.
Apparently, the parties behind Cyberbunker or sympathize with her anger over blocking action, then they counterattacked revenge.
Although Cyberbunker actually blamed for the attack, claiming to be a spokesman Cyberbunker, Sven Olaf Kamphuis, gave a statement that made the company become the accused.
The BBC, Kamphuis said Spamhaus should not be able to determine "what is permitted and not on the internet".
Steve Linford, Spamhaus's chief executive, told the BBC, said the scale of the attack was unprecedented. "We're under cyber attack for more than a week,'' he said.
"But they can not undermine us. Technicians we did a tremendous job to ward off the attack.''
Linford said the internet police forces from five countries now investigating the attacks.
