!Full Diagnostics limitationsThis report combines browser-based and hosted-service measurements; it is not a certified fault diagnosis.Expand disclaimerCollapse disclaimer⌄

Device performance, browser behaviour, Wi-Fi or mobile conditions, background traffic, VPNs, security software, routing, congestion and hosted-service load can affect every measurement. Repeat important checks under controlled conditions and compare them with your provider’s own evidence.

Important: Do not rely on this result alone for purchasing, configuration, security, safety, compliance, contractual or fault-diagnosis decisions. Results can be incomplete, delayed, misleading or wrong. Verify important findings with the relevant provider, manufacturer documentation and an appropriate independent test or qualified professional.

Network diagnostics

Full Diagnostics

Run one browser-based report covering responsiveness, diagnostic throughput, latency under load, stability, protocol details and browser capabilities.

Diagnostic setup

The report normally takes about 20–30 seconds. It can use up to approximately 640 MB download and 256 MB upload, although slower connections will generally use less.

Accuracy notice

This is a browser diagnostic estimate. HTTP requests are used instead of ICMP packets, the throughput phases are shorter than the dedicated speed test, and the score is not a certified ISP service-level measurement. The report may be incomplete, misleading or wrong and cannot identify every possible fault. Verify important findings independently before changing a live network, purchasing equipment or raising a contractual fault.

Your report will appear here

Start the diagnostics to measure the current browser-to-edge connection. Results can change with congestion, Wi-Fi or mobile signal, VPNs, device performance and background traffic.

Abuse protection

Confirm you are human

Complete this free security check before using bandwidth-heavy or technical diagnostic tools. It helps keep the service available without storing your public IP address in shared results.
