A large DDoS attack (distributed denial of service, means) has, this afternoon, a number of large sites on the east coast of the United States shut down. In such an attack, servers in a short time bombarded with so much data, that they traffic is temporarily unable to cope.
By the attack were large sites, such as Twitter, Spotify, Facebook and The New York Times in the region temporarily offline, or are less accessible. The problems are now over, and at over two hours long.
The cause lay in DNS provider Dyn. DNS (which stands for domain name system) is to compare with a phone book. Such a server ensures that people on the right place to end up when typing the domain name.
Amazon, in addition to a webshop server space rental, but had the same problems with DNS. The extent to which the two cases with each other is not yet clear.
Who is responsible for the attack at Dyn is unclear. Both companies have announced the problems to investigate.
