An argument between a group fighting internet junk mail and a Dutch company that provides hosting to websites accused of sending spam has reportedly led to internet speeds slowing.

Web monitoring site finds 'no evidence' of slowdown

Analysis of last nine days of internet speed test results at

There has been "no evidence" that UK users have experienced slower broadband speeds during a reportedly huge cyber attack over the last nine days, according to independent broadband news site

Rather than experiencing lower quality video streaming or longer buffering times, data showed that average speeds actually increased on Monday and Tuesday this week.

The information was collected by which allows users to test their connection speeds and see maps of the results.

War of words in anti-spam internet dispute

Web firm A2B, which has links to CyberBunker and is accused by Spamhaus of "knowingly selling internet connectivity to spam and crime outfits," has previously accused the anti-spam organisation of "propaganda" and "media spin".

It suggests Spamhaus, which helps other internet firms filter out spam and unwanted content, is guilty of online vigilantism without the backing of law or government mandate.

But Spamhaus chief executive Steve Linford told the BBC that Google and other large internet firms have provided resources to help it "absorb" the floods of traffic that are part of an attack.


Attack could take governments 'completely off the internet'

Spamhaus chief executive Steve Linford told the BBC that his organisation had been under cuber-attack for "well over a week."

"But we're up - they haven't been able to knock us down. Our engineers are doing an immense job in keeping it up - this sort of attack would take down pretty much anything else."

"If you aimed this at Downing Street they would be down instantly," he added. "They would be completely off the internet."

What is CyberBunker?

CyberBunker is thought to be behind large online attacks that have slowed internet services for millions of users.

Their action is in retaliation for being added to an anti-spam blacklist by Geneva-based Spamhaus.

What is CyberBunker?

  • Large Dutch-based web hosting firm which promises to support anything online except child pornography and terrorism
  • Claims to operate from an underground "Cold War era government command bunker" with 5,000 square metres of concrete-reinforced space
  • Says it supports freedom of speech and has large picture of Julian Assange on its homepage
  • Spamhaus accuses it of being a "rogue" host that supports spam, phishing and malware

Internet attacks 'increase in intensity'

  • Spamhaus has been described as an online vigilante group which tracks the internet's biggest spammers
  • But when Spamhaus added Cyberbunker, it retaliated, and flooded its servers with requests - at one point 300 billion per second
  • Because such attacks are increasing in intensity, computer experts say it could eventually mean people won't be able to reach basic services on the internet, including e-mail

A dispute between two European internet firms resulted in a global web slowdown today, it was claimed.

Geneva-based Spamhaus added Dutch hosting firm CyberBunker to an anti-spam blacklist, to which the latter responded with a large denial of service (DDOS) attack.

According to The Telegraph it meant millions of people found their internet experience slower than usual.
