By the numbers
Voidly Atlas aggregates 10,036 citable censorship incidents from 686,424 evidence rows. The corpus draws on 3.5B+ raw measurements from OONI, IODA, and CensoredPlanet, plus a probe fleet run by Voidly and community partners, whose live size and country coverage are published at api.voidly.ai/v1/probe/network.
Where the most incidents happened
Where the evidence comes from
No single measurement network captures the full picture. Voidly aggregates four independent sources so every confirmed incident has ≥2 corroborating signals — and structurally cites the upstream so journalists can audit our chain.
How accurate is our shutdown forecast?
Voidly Sentinel — the forecast model that powers /atlas/elections and per-country risk scores — publishes three honest accuracy splits so readers can choose which figure matches their risk tolerance.
| Split | AUC | F1 | Use for |
|---|---|---|---|
| Stratified (inflated) | 0.98 | 0.79 | Sanity check only |
| Time-based (floor) | 0.50 | 0.00 | Conservative baseline |
| LOCO median (honest) | 0.91 | 0.55 | Cite this |
