FlashStart Ranked as the World's Fastest Protective DNS According to Independent DNSPerf Benchmarks

DNS resolution represents the very first step for any web request: if you manage your company’s network infrastructure or operate as a Managed Service Provider, speed and security are crucial from the very first click.

In this landscape, FlashStart officially reaffirms its position as the fastest Protective DNS in the world, defining a new benchmark for cybersecurity and web browsing protection.

DNSPerf, the benchmark platform for DNS performance, certified this achievement, recording an average resolution time of just 13.51 ms for FlashStart and ranking it ahead of global giants such as Cloudflare, Google DNS, DNSFilter, and Cisco Umbrella.

This record is paired with strong operational continuity, featuring a 99.96% uptime, offering the perfect combination of responsiveness, reliability, and advanced enterprise filtering.

DNS Latency as a Key Metric for Network Speed

When discussing web performance, attention often centers solely on Internet connection bandwidth. In the operation of the Domain Name System, however, the true metric of efficiency is DNS latency.

Latency represents the actual reaction time: it is the interval, measured in milliseconds, required for the resolver to receive a request, verify security policies, and return the destination IP address.

Ensuring low DNS latency translates directly into fast browsing, reducing waiting times in every browsing session.

How Is Resolution Speed Measured on DNSPerf?

To ensure an impartial and representative evaluation of global performance, DNSPerf currently relies on a network of 413 test servers distributed across the globe for worldwide coverage.

The methodology is based on processing lists with substantial streams of DNS requests, sent directly to the servers under evaluation to assess their responsiveness. During testing, the platform detects resolution latency by timing the exact interval required to receive the response to each query sent. The final average latency figure synthesizes the response times of all completed requests, providing an objective measurement of real-world performance.

All technical details regarding the benchmark methodology are transparent and available in DNSPerf’s open-source repository.
