A fight between a spam-fighting group called Spamhaus and a Dutch Web host Cyberbunker has been called the biggest public DDoS battle in history in the news. Spam-fighting organization Spamhaus (helps to block spam from entering e-mail in-boxes) has been in a battle over the last week that has seen distributed denial of service (DDoS).
The attacks exceed by several times the typical attacks inflicted on organizations before. The DDoS That Almost Broke the Internet blog posting has lots of information on that recent attack Spamhaus DDoS attack and how CloudFlare helped mitigate it and keep the site online. The attack has causes peaking at 120Gbps of traffic hitting the network with help from open DNS recursors all over the world (including Finland). Unlike traditional botnets which could only generate limited traffic because of the modest Internet connections and home PCs they typically run on, these open resolvers are typically running on big servers with fat pipes. The operators of DNS servers should limit the networks from where they accept requests to stop this kind of problems.
