The Department of Homeland Security has begun an investigation into the DDoS (distributed denial-of-service) attack, the Guardian confirmed. The attack seemed to have been focused on Dyn, the company that runs the internet’s domain name system (DNS). Doug Madory, director of internet analysis at Dyn, said he was not sure if the outages at Dyn and Amazon were connected. “We began monitoring and mitigating a DDoS [distributed denial-of-service] attack against our Dyn Managed DNS infrastructure,” the company said on its website. “Someone is extensively testing the core defensive capabilities of the companies that provide critical Internet services,” he said.
