ControlD with Merlin

[yegor]

My problem with Control D was more than just the raw latency, which the human mind cant really perceive. It was actual pauses in lookups, pages taking 30 seconds to load or just giving up. Each time it happened I would go back to another DNS to test and it was fine. Go back to CD and after some time again lookups would just come to a crawl.

My fiber provider is changing soon so I will have a new opportunity to test out how it works.

That sounds highly irregular. Can you provide an example of such a behavior? dig/nslookup output and your ASN?

There is anti-abuse mitigations in place (as with all public DNS resolvers), but you have to reach hundreds of qps and sustain it for a while before it starts throttling you on free resolvers. Paid ones have higher limits.

I can relate with that.
Most of people I know which use controld, says the same thing.

Same as above.

I found ControlD to be the fastest service when I was located in an area with higher latencies. Also, when a couple of issues popped up, they were quick to respond and worked diligently to fix it. It was refreshing to get that level of personal service, even for the free services.
