How we measureEnglish
What the speed, latency, reachability and stability tests actually do inside your browser, how each number is derived, and the biases a browser-based test can't escape.

Censorship by region: why the same tool behaves so differently across bordersEnglish
Mainland China, Russia, Iran and Turkmenistan each block the internet in their own way, which is why the rankings are split by region. Here is what each system tends to target, how, and why that shows up directly in speed and stability numbers.

What is browser fingerprintingEnglish
A website can recognise you without a single cookie: collect a few dozen browser attributes, hash them, and you have a fingerprint. How it works, why entropy adds up, how fingerprints differ from cookies, and the thinking behind this site's "fingerprint authenticity" score.

WebRTC leaks: why your IP shows even with the VPN onEnglish
To set up peer-to-peer calls, WebRTC asks a STUN server what your public address looks like, and that request often slips past the VPN. How the leak works, why testing from China needs domestic STUN servers, and what turning WebRTC off costs you.

Canvas, WebGL and audio fingerprints: how your hardware gives you awayEnglish
Where the three most common hardware-related fingerprints get their variation, why the same machine looks different in another browser, and why noise-adding extensions usually make you more visible, not less. With a note on WebGPU.

Time zone, language and IP: how a site notices you're pretendingEnglish
Risk systems rarely decide on one signal. They check whether the time zone inferred from your IP, the one your browser reports, your system clock, the HTTP language header and the JavaScript language list agree with each other. Which mismatches are normal, and which get punished.

IP quality: residential, datacenter, and where the “proxy” flag comes fromEnglish
Beyond the country, websites classify your IP as home broadband, datacenter or mobile, and attach labels like proxy or hosting. Here is where those labels come from, why a VPN exit is almost always a datacenter address, and what that means for you in practice.

DNS leaks, open ports and TLS fingerprintsEnglish
Three side channels that are easy to overlook: name resolution slipping outside the tunnel, port 22 or 3389 open on your public IP, and the TLS handshake itself giving away your client. How each works, how this site checks them, and how to cross-check yourself.
