What does the checkup do?
It runs eight 1ms.dog tools one after another in this page and combines their results: Who Are You (what websites can tell about you), IP Quality Test, EgressLens (which exit each site sees), IPv6 Test, DNS Test, the Streaming & AI Unlock Check, the 1ms.dog service latency test, and the Speed Test.
Each tool runs in its own frame, shows its own progress and result, and hands the numbers to this page. Nothing is measured twice and nothing is simplified: the numbers here are the ones the tool itself shows.
Why three steps and about 90 seconds?
Latency and DNS measurements are sensitive to other traffic, so the bandwidth test runs last, alone. Step 1 runs the identity, IP, exit, IPv6 and DNS tests together; step 2 the unlock check and the service latency test; step 3 the speed test.
Each step waits for all its tools or 90 seconds, whichever comes first. A tool that doesn't answer in time is marked as not finished and left out of the grade.
How is the grade calculated?
Five sections, each graded A+ to F from its tools: IP quality counts 25 %, unlock 20 %, speed 20 %, identity and privacy 20 %, connectivity (IPv6, DNS, service latency) 15 %. The overall grade is the weighted mean of the sections that finished; a section that didn't finish is left out and the report says so.
A tool that grades its own result (IP quality, IPv6) keeps its grade; the others are scored from their facts: how many services work, how fast the download is and how much latency rises under load, whether anything leaks or mismatches, how quick DNS and the common services are.
What are the findings across the tools?
Some conclusions only appear when results are put side by side: a data-center IP together with a system time zone from another country (an incomplete disguise); AI services all blocked while the exit sits in a restricted region; split routing that sends AI and streaming through different countries; DNS in another region than the exit; latency that rises while downloading. Those appear at the top of the report.
Does my data leave my browser?
The tools run in your browser as usual; this page only receives their results through the browser's messaging between frames, and only from the tools it opened. The share link is built in your browser: it carries the grades and the tools' result links, never your IP address. Each tool's own result link follows that tool's privacy default, which leaves the address out.
How is this different from IPQuality or NodeQuality scripts?
Those scripts run on a server over SSH and can only test the server's own IP. This checkup runs in the browser, so it measures the connection you are on right now: your home line, your phone, a proxy or an airport node, with the browser's own view of time zone, language and WebRTC that a server script can't see. It also gives you a link and a card to share.
