In case you noticed your internet connection was wavering, and generally less speedy than what you paid for in recent days, you should not (necessarily) put blame to your provider. It might just be due to the immense distributed denial of service (DDoS) attack. Experts noted this might very well be one of the largest cyber-attacks of its kind ever, and the assault itself began on March 18. It was directed against The Spamhaus Project, an international non-profit organization that helps tracking and putting spammers and unwanted content they produce in Block Lists which are used in vast numbers of servers worldwide.

Attack were peaking at over 300 gigabits per second, which was "strong enough to take down government internet infrastructure." Steve Linford, chief executive of Spamhaus, explained to the BBC that they have been under attacks for well over a week, but they (attackers) have not been able completely stop Spamhaus?s DNS servers. Problem occurred due to the knock-on effect, which hurt the internet service globally. "If you imagine it as motorway, attacks try and put enough traffic on there to clog up the on and off ramps. With this attack, there?s so much traffic it?s clogging up the motorway itself," security expert Alan Woodward told the BBC.

As of now, identity of the attackers remains unknown, but everything could be related to the fact that Spamhaus recently put the Dutch web host CyberBunker into aforementioned Block Lists ? and this seems to be a retaliation for such action. CyberBunker was known to host "services to any Web site except child porn and anything related to terrorism" ? which provided a nice cozy home for spammers. Sven Olaf Kamphuis, who claims to be the representative of the CB stated that the Spamhaus is abusing its position, and that the Dutch web host, "in cooperation with criminal gangs form Eastern Europe and Russia is behind the attack." BBC tried to get a comment from CyberBunker directly, but there was no response.

Interestingly enough, CyberBunker is situated in a former NATO bunker, built back in 1995. The facility itself is made in a way it can operate in an energy saving mode completely cut off from the outside for more than ten years ? and owners call it "the most reliable datacenter in the world."

Thanks to the company Cloudflare that provides website performance and security services, Spamhaus survived the onslaught, and internet seems to be ?normalizing? for the moment being ? although popular services such as Netflix are still having issues. Cyber-police forces around the world are involved in the investigation to find the ones responsible for this attack.
