An online attack early in the US overwhelmed a service from internet-naming service provider Dyn, causing the websites of its customers, including major destinations like Twitter, Spotify, Github and Shopify to be unavailable to swathes of internet users for over two hours.
Dyn confirmed that a distributed denial of service (DDoS) attack affected its “Managed DNS” service on its status page:
This attack is mainly impacting US East and is impacting Managed DNS customers in this region. Our engineers are continuing to work on mitigating this issue.
The company restored service a few hours later:
Services have been restored to normal as of 13:20 UTC.
The company, an internet management company headquartered in Manchester, New Hampshire, said it began monitoring the attack at 11:10 UTC (7:10 ET) today. Since Dyn provides services around the internet’s domain name system or DNS, this means that users’ computers were unable or very slow to locate a given website address. The DNS is the same system that the US signed over to ICANN earlier this month.
