How this test works
This tool runs entirely in your browser, sending live DNS-over-HTTPS (DoH) queries from your local environment. No server-side code is involved, and no personal data is collected.
Warm-Up Phase: Before timing each DNS server, the script primes connections and caches to minimize TCP/TLS handshake overhead. This more fairly represents typical DoH performance once connections are established.
Measurement: We use fetch and
performance.now() to measure full DoH round-trip times. Results include HTTP/TLS
overhead, so they may be higher than raw DNS queries from other tools.
Timeouts: Each query times out after 5 seconds. Unresponsive servers appear as Unavailable and receive a 5000ms penalty to prevent skewing averages.
Variability: Network latency, bandwidth, and browser load cause variability. Run multiple tests at different times for a broader picture. Results are best used as a relative comparison among servers under your specific circumstances.
