Voidly OONI Censorship Historical

Historical OONI-derived daily aggregates and Voidly incident annotations for research. Aggregate rows are not individual measurements, and annotation rows are not a count of independently confirmed censorship events.

Files and schema

File	Columns and stored types
data/ooni-historical.parquet	country, test_name, date: string; measurement_count, anomaly_count, confirmed_count, failure_count, ok_count: int64; anomaly_rate, confirmed_rate: double
data/censorship-incidents.parquet	country, date, event: string; measurement_count, label: int64; anomaly_rate, spike_magnitude, confidence: double

At data revision e3419e2c54ded46ed8fefa89ac888b64cd74152a, both files' Parquet date statistics run from 2017-01-01 to 2026-02-05. These are file bounds, not a claim of continuous coverage for every country or test. Read the selected revision's file metadata and rows for its coverage; the repository's update time is not the measurement date.

The daily file contains country/test/day aggregates. measurement_count records the underlying sample count for a row. The incident file contains supplied labels, event names, spike scores, and confidence values. Those annotations do not by themselves establish ground truth or calibrated probabilities.

Use and limitations

Select the file or configuration that matches your task, and pin a repository revision for reproducible work. OONI measurement coverage varies by network, test, place, and time. Anomalous results can include false positives; consult OONI's interpretation guide before drawing censorship conclusions.

This archive does not establish the version or performance of a currently served model. Refer to individual Voidly model cards for their artifacts, evaluation methods, and limitations.

Source and reuse

The repository previously declared CC BY 4.0. OONI's upstream data license is CC BY-NC-SA 4.0. A single license covering all derived files and annotations has not been established here; check file provenance and applicable source terms before redistribution.
