A number of popular websites like Amazon, Twitter, Netflix and Spotify were down for some users on Friday morning in what appears to be a massive DDoS attack.
According to Hacker News, the outage is a result of an attack on Dyn’s DNS server, which is a company that manages domains.
The company noticed the attack shortly after 7am on Friday in New York. At that time, â€œwe began monitoring and mitigating a DDoS [distributed denial-of-service] attack against our Dyn Managed DNS infrastructureâ€, the company said in a public statement. Some customers may experience increased DNS query latency and delayed zone propagation during this time.
A DDoS attack — or denial of service — is an attempt to flood a website with so much traffic that it impairs normal service. Among the sites that appear to be affected include Twitter, Etsy, Github, Vox, Spotify, Airbnb, Netflix and Reddit.
No one has claimed responsibility for the attack yet. A government official said the U.S. is “looking at all possible scenarios including possible cyber activity.”
