Network Diagnostics Methodology

MethodologyTransparencyEditorial standards

Network diagnostics on TechUtilityTools rely on the browser's networking APIs combined with public endpoints.

Latency

Latency is approximated by issuing a small request to a known endpoint and measuring round-trip time. Browser scheduling, connection reuse, and TLS handshakes can affect first-sample readings.

DNS

DNS lookups are performed via DNS-over-HTTPS providers. Results reflect the DoH resolver's view, which may differ from the user's local resolver.

Connectivity

Connectivity checks combine fetch behavior, navigator.onLine, and timing of small probes to estimate effective reachability of public endpoints.

Bandwidth and timing

Bandwidth is estimated using sized payload transfers, with adjustments documented per tool. Browser caching and HTTP multiplexing affect observed throughput.

Browser APIs

Where available, Network Information API and Performance API timings are used to enrich results. These APIs are not available in every browser.
