## What we cannot say

- **Who caused it** — measurement data alone does not attribute the interference to any government, ISP, or other actor.
- **Intent** — anomalous or unreachable measurements indicate interference, not a stated motive or a deliberate-vs-incidental determination.
- **Sub-national scope** — measurement is aggregated at the country level; we cannot localize to a province, city, or network segment.
- **Independent corroboration** — multiple qualifying evidence source labels do not establish target/time agreement or source independence.
- **Whether this is censorship** — this is a connectivity *disruption* (outage) signal, not confirmed intentional blocking.

## Data Sources

censoredplanet, ioda

These source labels come from qualifying linked evidence. Historical incident source labels and quarantined observations are excluded; multiple labels alone do not establish independent corroboration.
