only ever failed — the ones we lose
Where installs are lost
Unique devices at each stage. This is the whole point: 'never moved a byte' is unreadable until you can see whether they never opened it, never pressed connect, or pressed connect and got nothing.
Why connections fail
Failure class, by unique device — the fix list, most common first
Silent failures by type
Failures that raise no browser error and would never appear in a feedback form
Failures by exit node
Our own boxes — a node far worse than its neighbours is a box to fix, not a mystery
Health by exit location
A country failing far more than the rest is a fleet problem, not a user problem
State at uninstall
What the extension last knew about the tunnel when it was removed
Net installs by platform
Unique devices seen installing, minus those that reported an uninstall. Never blended across platforms.
