The Digital Attack Map is a live data visualization, built through a collaboration between Arbor Networks and Google Ideas, that maps “distributed denial of service” (DDoS attacks) designed to take down websites around the globe. Many websites face targeted digital attacks by people who aim to silence their speech. This tool and visualization specifically surfaces anonymous traffic data related to these attacks, letting people explore historic trends and see related news reports of outages happening on a given day. (via Google+)
