A coordinated cyber-attack has hit a large sector of the internet, and that has made services like PlayStation Network, Netflix, and Twitter inaccessible for a significant number of people. Earlier today, a distributed denial-of-service assault hit domain name system (DNS) service Dyn. That is preventing many heavily trafficked sites from loading for people around the world.
That earlier attack subsided for a few hours, but it has returned and is affecting sites that serve millions of users and customers.
The DynDNS is one link in a chain that enables the internet to function. It enables your browser to understand that when you type something like “netflix.com,” you want to go to a certain IP address. By assaulting the Dyn system, however, this cyberattack is preventing that connection from happening. Affected services include:
- PlayStation Network
But since these switchboards of the web are so interdependent, one going down can cause the others to collapse.
