Dogecoin fork event : hit with an NTP DDoS Amplification attack!
Dogecoin fork event , We need to be vigilant. They were hit with an NTP DDoS Amplification attack!
Dogecoin Pools -
February the 5th 2014 at 12:37 GMT+1 We were hit with an NTP DDoS Amplification attack!
What is an NTP DDoS attack? We usually get 2-3 DDoS attacks per day , but not that big. They usually reach up to 50 or 75gbits tops.
As soon as the DDoS Hit we tried to mitigate the attack. Our failover balancer automaticly switched to new ips for the stratum and web , however the attack followed the DNS change immediately.
The attack was constantly growing so our upstreams had no other choise but to null route(blackhole) us as soon as it reached more than 150gbits
The peak of the attack was close to 200gbits , with millions of packages per second.
Understanding and mitigating NTP-based DDoS attacks
Ref: Cloudflare report.
Two days later : biggest attack yet
As you may know we fell victim to a big DDOS attack causing the server to be unreachable.
I’m adding one week to all subscriptions to make up for the downtime.

Nasty. I can imagine this could effect Mining pools etc and even this forum / website but the feathercoin network should be ok? Is this correct?
