Record-Breaking DDoS Attack Slows Web
Spamhaus tracks the Internet's spam operations and sources, and maintains real-time, spam-blocking databases that help Internet networksweed out bogus email. Trouble started, however, when Spamhaus added a firm known as Cyberbunker to its blacklist, the BBC said.
Spamhaus said last week that it experienced a "large-scale DDoS attack" over the course of several days, knocking out its website and mail systems. By Friday, March 22, Spamhaus said all its systems were "green" and back online.
That was due, in part, to CloudFlare, which published a blog post that went into greater detail about the attack. "Spamhaus signed up for CloudFlare ... and we immediately mitigated the attack, making the site once again reachable," the company said.
CloudFlare, however, said it logged attacks that topped 75 Gbps, while the New York Times and the BBC said those attacks actually reached 300 Gbps. For comparison, a "normal" DDoS attack that might take down a bank website, for example, is around 50 Gbps, the Times said.
"It was sufficiently large to fully saturate [Spamhaus's] connection to the rest of the Internet and knock their site offline," CloudFlare said.
"These very large attacks, which are known as Layer 3 attacks, are difficult to stop with any on-premise solution," CloudFlare continued. "Put simply: if you have a router with a 10Gbps port, and someone sends you 11Gbps of traffic, it doesn't matter what intelligent software you have to stop the attack because your network link is completely saturated."
This makes it "one of the largest computer attacks on the Internet," the Times said; the BBC echoed that sentiment, calling it the "biggest cyber-attack in history."
As a result, some sites - like Netflix - have seen some slowdowns, the sites reported. Spamhaus is reportedly now working with various law enforcement agencies around the globe.
Spamhaus and Cyberbunker did not immediately respond to a request for comment.

Bias DDoS attacks will probably start showing up more now.
I don't think this will affect the amount of DDoS attacks.

Honestly, since I'm a computer hacker & such, one would assume that I think this is cool, but it really isn't. Sending a DDoS to one person is one thing or being a hacktativist s one thing but to send out such a large attack that it flicks up the whole internet for no reasonable purpose is just plain stupid. People on here who don't know the details about hacking and such are the ones who post that this is awesome, seriously? This shuts down basically half the web which really **** up a lot of organizations who do sales or trade online. I don't support such a large scale attack, simply because it had no meaning. I do however suppor hacktaivist, this affected innocent companies aswell as Xbox Live and PSN.

Brad- Pretty cool that they had the ability to do this, imagine if all of the major hacking/spamming companies joint together to DDoS together. Now THAT is something that could boot the whole internet offline!
Now that would be annoying, yet very funny at the same time
Yeh that would be really funny. Its not hard to DDoS one person but it must be hard to kick the "Whole" internet ofline haha

KerriganMaya-Fluttershy-DLT They are lucky they have such a large data network spread all over the globe.
THey must have had so many people DdoSing at once. just think. 300gb worldwide.
I know dude, thats crazy.
You don't need multiple people, just a very large botnet.
Srizbi botnet had around 450,000 infected computers but was used for a different purpose.
