Controversial information disclosure site Wikileaks reportedly faced an intense distributed denial of service (DDoS) attack this morning. The site was temporarily disrupted by the onslaught, but is functioning again after migrating its services to Amazon's cloud.

Wikileaks recently published thousands of confidential diplomatic cables that were sent between the US State Department and embassies around the world. The leaked documents shed light on US intelligence gathering efforts and reveal sensitive information pertaining to US foreign relations. The disclosure of the cables has proved embarrassing for the US and a number of other governments.

It's possible that the DDoS against Wikileaks was orchestrated by a government in effort to retaliate against the leak and disrupt access to the documents. Prominent figures in the US government, including a congressman, are calling for an extreme response to the leak, arguing that Wikileaks should be treated as a terrorist organization. The group is clearly facing considerable pressure and close scrutiny as a result of the leak.

Wikileaks says that the DDoS was pummeling its servers at 10 gigabits per second, forcing its Swedish hosting provider to discontinue operation of the site. In order to continue operating smoothly, Wikileaks moved its site to Amazon's elastic cloud computing infrastructure. This will allow it to scale better in the face of massive DDoS attacks.
