Confirmed blocking by country
Ranked by the share of measurements where blocking was proven — a block page was served, or a DNS answer pointed somewhere it demonstrably should not. Countries with fewer than 1000 measurements in the period are left out, because a handful of probes in a bad hour can produce a striking percentage that means nothing.

Confirmed and anomaly are deliberately separate columns. An anomaly is a measurement that looked wrong but could not be proven — ordinary network trouble produces those too. Adding the two together gives a bigger, more quotable number and an untrue one.
Download the data
All 149 countries, not just the table above. Free for any use, including commercial and journalistic — no attribution to us required, though OONI's licence asks for attribution to them.
Method
The measurements come from OONI,
the Open Observatory of Network Interference, which runs volunteer probes in
over 160 countries and publishes the results openly. We query their
aggregation API for the web_connectivity test, which asks a
single question: could this site be reached from here?
We store a snapshot rather than querying live, so the numbers on this page do not move while you are reading them or while someone is citing them. The snapshot is refreshed weekly.
What this is not: a ranking of how censored a country is. Probe coverage is uneven, volunteers test the sites they care about, and a country with more engaged volunteers will show more of everything. It measures what was tested, which is not the same as what exists.
Per-site data
This page counts blocking per country. If you need it per website — which domains were measurably blocked where, month by month — that is published as an open dataset, one CSV per month, rebuilt from the same OONI measurements.
