Stockholm: WikiLeaks said in a Twitter message today that it was under a new cyber attack after a similar incident at the weekend just before the website began
releasing secret US diplomatic cables.
"We are currently under another DDoS attack," WikiLeaks said on its official Twitter feed.
DDoS stands for distributed denial of service. Classic DDoS attacks occur when legions of "zombie" computers, normally machines infected with viruses, are commanded to
simultaneously visit a website.
Such a massive onslaught can overwhelm servers, slowing service or knocking it offline completely.
A later message on the WikiLeaks twitter said "DDoS attack now exceeding 10 gigabits a second."
On Sunday, just as it began the release of some 250,000 US embassy cables, WikiLeaks said on Twitter the website had come under a DDoS cyber attack.
But it insisted El Pais, Le Monde, Der Spiegel, The Guardian and the New York Times would go ahead with the publication of the first of such documents even if the
WikiLeaks website was down.
As of 1600 GMT yesterday, both websites were still online.
