If you live on the East Coast and had trouble accessing Twitter, Spotify Netflix, Amazon or Reddit Friday morning, you were not alone. At least two successive waves of online attacks blocked multiple major websites Friday, at times making it impossible for many users on the East Coast to access Twitter, Spotify, Netflix, Amazon, Tumblr and Reddit.
The first attacks appear to have begun around 7:10 am Friday, then resolved towards 9:30 am, but then a fresh wave began. The cause was a large-scale distributed denial of service attack (DDoS) against Internet performance company Dyn that blocked user access to many popular sites standstill.
