WikiLeaks is back online following a week of downtime caused by a prolonged distributed denial of service (DDoS) attack.

The whistle-blowing site managed to get back online thanks to CloudFlare, a cloud computing performance and security vendor. On its Twitter page, WikiLeaks said CloudFlare had helped with additional capacity, enabling it to get back online.

According to TechCrunch, WikiLeaks was back up and running minutes after signing up for CloudFlare. According to that report the service works by routing all traffic to a user’s site through CloudFlare’s servers, which then filter out illegitimate traffic.

Shortly after the site came back online, WikiLeaks posted a defiant message on its Twitter page: "Is that all you’ve got? Keep attacking, our skin just gets harder. DDoS proof, financially & geographically diverse. We’re ready to rumble."

There is still an element of uncertainty over who was behind the attacks. A group calling itself AntiLeaks claimed responsibility for the DDoS, and said it was a response to Julian Assange’s claim for asylum in Ecuador, which is expected to be resolved soon.

However the attacks coincided with the release of a new batch of emails hacked from Stratfor. The latest releases concern TrapWire, surveillance technology which it is claimed is being used by the US and UK government to monitor citizens in an attempt to spot any terrorist activity.
