A massive cyber attack Friday brought down some of the internet’s most popular websites, including Twitter, Spotify, and PayPal among others.

The DDoS (distributed denial of service) attack targeted Dyn’s DNS service. The company manages website domains, and such attacks are attempts to flood websites with so much traffic that they’re effectively unable to function.

Tech news forum Hacker News said Friday’s DDoS attack also affected Etsy, Github, Vox, Spotify, Airbnb, and Reddit, making them inaccessible or disabling much of their functionality.
