The site WikiLeaks asked its “supporters” on Friday to stop taking down the internet in the U.S. following a massive distributed denial of service (DDoS) attack that disrupted a number of major sites.

“Mr. Assange is still alive and WikiLeaks is still publishing,” the site tweeted. “We ask supporters to stop taking down the US internet. You proved your point.”

Two domain name system tools, DynDNS and Amazon Web Services, reported earlier that they had experienced outages. DynDNS had attributed its outages to a DDoS hack, while AWS has yet to identify the cause to its own disruptions.

The Department of Homeland Security said that it is investigating the incident but has not pointed to any suspects.

The WikiLeaks tweet raises the possibility that the attacks could be retaliation for Julian Assange’s internet connection being severed by the Ecuadorian Embassy in London, where Assange has been living since 2012 to avoid a rape charge in Sweden that he denies.
