DNS Landscape in Argentina
Argentina has a developing internet infrastructure with major ISPs like Fibertel, Personal, Telecentro, and Movistar. DNS peering is limited compared to North America or Europe, which means some international DNS providers show higher latency. The country relies heavily on ISP-provided DNS, but many users are switching to public resolvers for better speed and reliability.
Cloudflare has some presence in the region, but not as strong as in the US or Europe. Google DNS benefits from Google's cache infrastructure in South America. Choosing the right DNS in Argentina can cut page load times meaningfully, especially for users on slower DSL connections.
Performance Rankings for Argentina
Google DNS (8.8.8.8) is the fastest option for Argentine users, averaging 8-12 ms from Buenos Aires. Cloudflare (1.1.1.1) averages 10-15 ms. Quad9 (9.9.9.9) averages 18-25 ms. OpenDNS averages 22-30 ms. Fibertel's default DNS averages 15-22 ms. Personal DNS averages 18-25 ms.
Google leads in Argentina because of its South American CDN presence. Cloudflare is a close second and may perform better for non-Google services. Both are a significant improvement over ISP defaults for most users.
Buenos Aires Test Results
From Buenos Aires, Google averaged 9.5 ms. Cloudflare averaged 12.3 ms. Quad9 averaged 20.1 ms. Cordoba showed Google at 10-14 ms and Cloudflare at 13-17 ms. Rosario results were similar to Cordoba. The interior cities see slightly higher latency due to longer routing paths to international peering points.
