Results Summary

TLDR / Summary

  • All providers (except Yandex) performed very well in North America and Europe. They all had under 15ms response time across the US, Canada and Europe, which is amazing. In reality, you can choose any one of them and do not notice the few msec of latency difference. However, Asia and South America made the difference in the overall averages (and finding the winner) as some of the providers are not well connected there.
  • CloudFlare was the fastest DNS for 72% of all the locations. It had an amazing low average of 4.98 ms across the globe.
  • Google and Quad9 were close for second and third respectively. Quad9 was faster than Google in North America and Europe, but under performed in Asia / South America.
  • CloudFlare has a strong presence everywhere. While Google and Quad9 had some high response times from some locations, CloudFlare performed well from everywhere.
  • Yandex is only for Russia. It doesn't leverage Anycast like the other providers, and was very slow from everywhere.
  • CleanBrowsing was the fastest provider offering adult (porn) content filtering.
  • We know we can't compare these providers 1 to 1, as they all have special features that can add some latency (Quad9 and Comodo blocks access to malicious domains, for example). Take the results as is.
