Dyn DNS is reporting a large-scale DDoS attack on it's servers this morning, which has caused sporadic interruptions of service for users, mainly on the East Coast of the US. Github, Twitter, and Reddit all use the service as their upstream DNS provider and have reported many outages and total downtime lasting hours. DynDNS president released a statement saying:
This morning, October 21, Dyn received a global DDoS attack on our Managed DNS infrastructure in the east coast of the United States. DNS traffic resolved from east coast name server locations are experiencing a service degradation or intermittent interruption during this time. Updates will be posted as information becomes available.
Upon recognition, active mitigation protocols were initiated and have been working to resolve the issues.
Customers with questions or concerns are encouraged to check our status page for updates and reach out to our Technical Support Team.
No information was available as to whom might be behind the attack, leading to speculation that it may have been launched to protest the recent arrest of an aspect of Peace on Earth earlier this week.
