I recently considered moving my relay nodes to a different VPS provider.
the problem is - that VPS provider offers no DDOS protection.
Has anyone experimented with cloudflare’s DDOS protection for their nodes?
Do you guys think its important to have DDOS protection for relay nodes?
I don’t think this is really anything to worry about. The purpose of a DDOS is generally to bring down a service. In the case of a single node, it would have zero impact on the overall network. The attack is pointless against a single node, except maybe if there was an extortion angle, but you could simply move your node to a new IP.
DDOS attacks are also somewhat expensive to launch, so there is always the option of just waiting it out as well.
Every little bit helps… its only $10/month. Do I think somebody can bring down the Cardano network? No. Do I think somebody could bring down my servers? Yes. My liability is to my future investors (delegators) who trust my ability to maximize their return.
I just don’t see any pay off for launching a DDOS at any particularly pool. The only “useful” vector would be hitting the current leader to prevent minting a block, which would require some sophistication. Even then, I don’t know that it would even be useful in any real capacity.
I just don’t see the monetary reward for the attacker, so why would they waste resources on such an attack?
A sustained attack from a rival pool kinda makes sense if your goal was to force delegators to leave. It would have to last many epochs, so it’s highly cost prohibitive. Even if you could pull that off, delegators would migrate to many different other pools, so the payoff is zilch again.
