Voidly / Observatory

From interference
to evidence.

A connection fails. The harder question is why. Voidly brings measurements, source records, and network context together so restrictions can be examined and cited.

Snapshot: . Read the coverage definitions and sources. Sample availability varies by country and time window.

The method

Keep the observation.
Test the interpretation.

The observatory combines Voidly probe observations with external measurement projects. DNS, connection, TLS, and HTTP results describe where communication fails; routing and connectivity signals provide wider outage context.

A failure can also come from a misconfigured service, an unreliable network, or the measurement itself. Sources, dates, status, and confidence belong with the finding. An anomaly alone does not establish censorship.

Read the current methodology

The evidence path

Observe. Correlate. Inspect.

  1. 01 / Measurements

    Retain the context.

    Keep the source, time, location scope, and tested service attached to each observation.

  2. 02 / Evidence

    Resolve the signals.

    Group related observations, compare independent sources where available, and preserve uncertainty.

  3. 03 / Public record

    Make it inspectable.

    Expose incident records, evidence links, country summaries, and machine-readable access.

Not every incident has multiple sources. The public record distinguishes suspected events, citable records, linked evidence, and independent corroboration. Inspect those categories.

Source foundation

Different views of the same network.

Source attribution describes data provenance. Each project has its own coverage, methodology, update schedule, and reuse terms.

Use the record

For a source note.
Or a software pipeline.

Start with the country or incident explorer. Move into JSON, downloadable datasets, or a developer integration when the work calls for it.

Engineering archive

The work behind the interface.

Technical notes on measurement, classification, and distribution. These articles preserve earlier designs and experiments; their historical metrics and architecture descriptions are not current service guarantees. Use the linked source records above for present coverage and the current methodology for model limitations.

Measurement & probe design / 8 notes
Classification & evidence / 9 notes
Data & developer access / 7 notes

Reuse & citation

Carry the source forward.

Voidly-original scores, incidents, and annotations use CC BY 4.0. Raw upstream material retains its own terms, including CC BY-NC-SA 4.0 for OONI raw data and Citizen Lab test lists. Software has separate licenses.

Replace the access date with the day you retrieved the data. Include the source record and observation date for a specific finding.
