Usually people blame slow-loading websites on a slow Internet connection, but as recently discovered, it could be the outcome of a large global cyberattack. 

Spamhaus (The European nonprofit spam filtering company) reportedly is fending off distributed denial-of-service (DDoS) attacks, that rapidly took the site temporarily offline and is causing Big congestion on the Web.

At the begging of the attack, the company was overwhelmed with traffic, and turned to the security team at CloudFlare to get the site running again. Until now, the attackers are overwhelming Spamhaus with traffic with scale that has reached 300Gbps. normally, it only requires 50Gbps to pull off a severe attack to take down a normal website. What makes it so hard to stop or at least slow down the attack without turning off those servers and stop the Internet is traffic that is coming from servers all over the world. 
Spamhaus creates blacklists of servers which spammers utilize to send messages for e-mail providers, so providers would be able to filter spam for users. Spamhaus recently combined CyberBunker hosting company and its ISP, A2B Internet, to its list.

Although, it’s really difficult to determine for sure who is responsible for the attack, CyberBunker’s Sven Olaf Kamphuis is reportedly taking credit, according to New York Times and BBC. When it comes to web hosting, CyberBunker has a philosophy of anything-goes which rejects only terrorism-related material and child pornography. 
CyberBunker’s site explains the conflict with Spamhouse, alleging that it was torrent tracker services and Chinese-based customers peddling replicas that garnered the spam filter’s ire, not anything more outrageous. However, this is not the first time CyberBunker has come under fire; it was also its site that report the story of a SWAT team invasion of its Cold War-era nuclear bunker headquarters.

According to Kaspersky Lab Security Company, attacks of this kind are escalating in frequency and scale, which of course is very bad news for Web-surfers. According to Kaspersky global research and analysis team, data flow generated by the attack may affect the nodes of intermediate network when it passes them, Consequently, impeding operations of normal Web services that don’t have any relation to CyberBunker or Spamhaus . This will assist DDoS attacks to go further and affect regular users as well.
