Aggregate Voidly's confirmed national blocks by world region and you get a striking-looking table: Asia 1,545, Europe 891, the Americas 29, and Africa and Oceania at zero. The tempting read — “Africa barely censors the internet” — is wrong, and understanding why is the whole point of running an honest observatory. The confirmed-block map is not a censorship map. It is a measurement-density map.
The numbers
| Region | Countries measured | Block fraction | Confirmed national blocks |
|---|---|---|---|
| Asia | 46 | 0.85 | 1,545 |
| Europe | 31 | 0.73 | 891 |
| Americas | 22 | 0.30 | 29 |
| Africa | 28 | 0.60 | 0 |
| Oceania | 5 | 0.00 | 0 |
Africa blocks plenty — it just can't be confirmed
Look at the contradiction in Africa's own row: a 0.60 block fraction across 28 countries and 4,600+ measurements — blocking is plainly being observed — yet zero confirmed national blocks. That is not a paradox; it is the confirmation standard doing its job too well for the data available. A “confirmed national block” requires a domain to be seen blocked across at least three independent networks (ASNs) in a country. That gate exists to keep one flaky vantage point from being mistaken for nationwide censorship (see the detection-gate finding). But it has a price: it can only confirm what is densely measured. Where a country is probed from only one or two networks, a very real block never reaches three ASNs, so it stays an unconfirmed signal — not a confirmed block.
The map you're really looking at
Asia and Europe top the confirmed-block table partly because they are the most heavily censored regions — but also because they are the most heavily measured, with dense OONI/probe coverage across many networks per country. Africa and Oceania sit at zero not because their internet is free, but because the multi-network coverage needed to confirm a block at the three-ASN bar isn't there yet. Read the confirmed-block counts as a floor on what we can prove, never as a ranking of how censored a region is. The blind spots are blind spots, not freedom.
Why this matters — and what we're doing about it
A censorship observatory that quietly let “0 confirmed” read as
“0 censorship” would systematically erase exactly the regions with
the least measurement infrastructure — often the ones that can least
afford to be invisible. So Voidly reports the block fraction and the country
coverage right alongside the confirmed count, and it is actively widening
measurement density: the probe network recently expanded from a 62-domain
default to the full multi-thousand-domain Citizen Lab list across dozens of
global vantage points. More networks per country is the only thing that turns
an unconfirmable African block into a confirmed one. Until the coverage is
even, treat the regional confirmed-block map as a measurement map —
because that is what it is. Live data: GET /v1/measurement/by-region.
