Washington (CNN) -- After posting thousands of secret government documents, WikiLeaks came under an electronic attack designed to make it unavailable to users, the whistle-blower website said Tuesday.
The site also experienced a distributed denial of service (DDOS) attack on Sunday, just as it was publishing the first of what it says are 250,000 secret U.S. diplomatic cables. Such attacks normally are done by flooding a website with requests for data.
"DDOS attack now exceeding 10 Gigabits a second," WikiLeaks said on Twitter.
The effects of Tuesday's electronic disruption were unclear.
WikiLeaks recovered from Sunday's disruption and began publishing cables from U.S. embassies around the world, documents that the website said represented the largest-ever disclosure of confidential information. Those documents give the world "an unprecedented insight into the U.S. government's foreign activities," the site said.
WikiLeaks drew widespread condemnation for publishing the confidential cables that in some instances, detailed with unusual frankness Washington's diplomatic interactions with other countries.
