What is a DDoS Attack?

A Distributed Denial of Service (DDoS) attack is an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources. They target a wide variety of important resources, from banks to news websites, and present a major challenge to making sure people can publish and access important information.

DDoS Attacks Matter
Distributed Denial of Service (DDoS) attacks can be used to make important online information unavailable to the world. Sites covering elections are brought down to influence their outcome, media sites are attacked to censor stories, and businesses are taken offline by competitors looking for a leg up. Protecting access to information is important for the Internet and important for free expression.

Visualizing Trends
Understanding the raw data behind DDoS Attacks is not intuitive. As a result, the impact, scale and scope of the challenge can be easily overlooked. We hope this tool allows more people to understand the challenges posed by DDoS attacks. We also hope it triggers a dialogue about how we can work together to reduce the threat of DDoS Attacks, improving the Internet for everyone.
