Dyn Confirms DDoS Attack Affecting Twitter, Github, Many Others

DNS provider Dyn has confirmed a massive distributed denial of service attack against its servers early Friday impacting many of its customers including Twitter, Spotify and GitHub.

“This attack is mainly impacting U.S. East and is impacting Managed DNS customesr in this region. Our engineers are continuing to work on mitigating this issue,” according to a statement by the company to customers.

Dyn said that as of 9:36 a.m. Eastern time, its services were restored and many of its affected customers, including Twitter, were back online.

It’s unclear how many sites had been impacted. For hours Friday morning many popular sites appeared to be experiencing outages or extremely sluggish performance including Twitter, Etsy, Github, SoundCloud, Spotify, Heroku, PagerDuty and Shopify. Dyn representatives would not confirm if each one of these outages was tied to the DDoS attack.

Manchester, New Hampshire-based DYN said it first began monitoring the DDoS attack at 7:10 AM (ET) Friday.  The company said in a statement to customers:

“Starting at 11:10 UTC on October 21th-Friday 2016 we began monitoring and mitigating a DDoS attack against our Dyn Managed DNS infrastructure. Some customers may experience increased DNS query latency and delayed zone propagation during this time. Updates will be posted as information becomes available.”

It’s unclear, at this time, the source of the DDoS attack, Dyn said.

An outage map posted by the telecommunications firm Level3 Communications shows a massive outage in the Northeast.
