What We Know About Friday’s Massive East Coast Internet Outage
This Is Why Half the Internet Shut Down TodayFRIDAY MORNING IS prime time for some casual news reading, tweeting, and general Internet browsing, but you may have had some trouble accessing your usual sites and services this morning and throughout the day, from Spotify and Reddit to the New York Times and even good ol’ WIRED.com. For that, you can thank a distributed denial of service attack (DDoS) that took down a big chunk of the Internet for most of the Eastern seaboard.
This morning’s attack started around 7 am ET and was aimed at Dyn, an Internet infrastructure company headquartered in New Hampshire. That first bout was resolved after about two hours; a second attack began just before noon. Dyn reported a third wave of attacks a little after 4 pm ET. In all cases, traffic to Dyn’s Internet directory servers throughout the US—primarily on the East Coast but later on the opposite end of the country as well—was stopped by a flood of malicious requests from tens of millions of IP addresses disrupting the system. Late in the day, Dyn described the events as a “very sophisticated and complex attack.” Still ongoing, the situation is a definite reminder of the fragility of the web, and the power of the forces that aim to disrupt it.

Today there is an ongoing, large scale Denial-of-Service attack directed against Dyn DNS. While Cloudflare services are operating normally, if you are using both Cloudflare and Dyn services, your website may be affected.
Specifically, if you are using CNAME records which point to a zone hosted on Dyn, our DNS queries directed to Dyn might fail making your website unavailable, and presenting a “1001” error message.
Some popular services that might rely on Dyn for part of their operations include GitHub Pages, Heroku, Shopify and AWS.
