Why does a VPN work for a few minutes, then just stop?
A VPN that connects fine but dies minutes later usually isn't a full block. It's active probing. Here's how that works and what actually gets past it.
Field notes
Privacy engineering, censorship, and honest updates from a deliberately small VPN. English only for now.

How do you verify a VPN's no-logs claim?
A VPN breach leaked connection logs despite a public no-logs promise. Here's what actually proves a no-logs claim, and what doesn't.

Why did my VPN suddenly stop working in China?
VPNs in China usually stop working because the filter learned to recognise the protocol, not because your server IP was banned. Here is how to tell which one happened.

Why does my VPN work on mobile data but not on school wifi?
If your VPN connects on 4G but fails on campus or school wifi, the network is filtering it. Here is how to tell which of four methods is doing it.

Can a VPN work when the network only allows ports 80 and 443?
Restrictive wifi often permits only outbound 80 and 443. Here is why most VPN protocols die there, and the engineering we did to get three transports onto 443.

Why does my VPN connect but nothing loads?
Your VPN says connected and pages hang forever. Four causes: DNS, MTU, a captive portal, and a network that lets the handshake through then kills the tunnel.

A warrant canary is only worth the day someone checks it
Most VPN privacy claims have no test attached. Here is what a warrant canary actually is, what it cannot do, and how to check ours and everyone else's.

Does deep packet inspection detect WireGuard?
Yes, and it is not difficult. WireGuard's handshake is fixed-size with a constant header, and the protocol deliberately leaves obfuscation to someone else.

What is active probing?
Some censors do not just watch your traffic. They connect to your server afterwards to see how it answers, which defeats obfuscation that only fools a passive observer.

Why your school wifi blocks your VPN
Campus filters do not work from a list of VPN server addresses. They recognise the shape of the connection, which is why changing server never helps.

Why your VPN stopped working in Russia
The blocking moved from addresses to protocols. That is why switching servers stopped helping, and why some VPNs fail while others keep connecting.

Your WireGuard public key might outlive your VPN session
WireGuard rotates traffic keys, not peer identity. We traced Pangea's key from provisioning to disconnect and found that it lives longer than we thought.

Paying for a VPN without telling it who you are
Most VPN signups collect an email and a card before they encrypt a single packet. Here is what that record is, why it leaks, and how the crypto path works at Pangea.

A logging policy is a promise. The client is a fact.
Nobody can verify a VPN's logging policy from outside, including ours. Here is what you can actually check about Pangea yourself, and what you can't.
