What if you have a few bad users which hammer one of the PowerDNS Recursor servers? It will surely degrade service quality for all users which are routed to this same server. I found that I can more easy distribute or filter the load using dnsdist. How do you monitor the correct working of a PowerDNS Recursor? At what point do you decide to stop an anycast announcement for a server? I found that our service is more stable when using dnsdist with multiple backend resolvers during network stability issues. Or to put it in numbers. In our old setup without dnsdist we had 1 or 2 events per year with short regional service degradation. Since using dnsdist in early 2016 there have been none.
