This query · JSON Incident RSS Methodology
Dates, classifications and reuse

Observation dates belong to each source record. Source-generation time is when the API assembled its response; it does not mean that every listed event is recent or still occurring. This page requests the source when loaded and does not continuously refresh.

“Censorship,” “disruption,” status and mechanism are source classifications. A network disruption alone does not establish intentional censorship. Check evidence, coverage and attribution before drawing conclusions.

Voidly-original incidents and annotations are CC BY 4.0. Upstream measurements retain their own licenses. Use the canonical incident URL, observation date and source when citing; each detail page provides citation downloads.

Dataset version: 2026.10.11. Page source check: .
