The masterlist 2.0 server is showing about 50% of the servers refusing queries so I've lowered the request time to a 3 minute period just to ease the load a bit (at first I was worried the service scaled to more nodes and was inadvertently DDoSing the entire community!)
For more mitigation methods, take a look at rate limiting UDP packets - it's not so common as TCP as it's usually used in the microservices/API scenarios but iptables and hardware firewalls should support it. |
The rates are around 100 per second, which is not that much, but still problematic.
