It’s apparently possible that a DDoS attack can be big enough to break the internet — or, as shown in the attack against ISP Dyn, at least break large parts of it.
The DDoS attack against Dyn that began Friday went far past taking down Dyn’s servers. Beyond the big-name outages, organizations could not access important corporate applications or perform critical business operations.
As one of the largest ISPs in the world, Dyn going offline took down a significant chunk of the DNS, the internet’s address directory.
