- A coordinated Internet attack has taken a wide variety of sites offline for millions of users today.
- The incident, a distributed denial-of-service attack on traffic company Dyn, came against the domain name system infrastructure that helps connect users to sites, and it's coming in waves: After earlier outages, Dyn has warned that it's under assault again.
- The earlier attack took a number of sites off line for hours, including Amazon (AMZN +1%), Twitter (TWTR -0.3%), Etsy (ETSY -0.8%) and Spotify (MUSIC) as well as many more.
- The Department of Homeland Security says it's "looking into" the attack.
