## Metrics

- Confidence: 72%
- Measurements: 3
- Anomaly Rate: 83.3%

## Evidence

- **OONI** (measurement): OONI whatsapp: 1/1 measurements anomalous (100.0%)

- **OONI** (measurement): OONI http_invalid_request_line: 1/1 measurements anomalous (100.0%)
  - Observed: 2026-05-05
  - Confidence: 90%

## 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.
- **Which networks** — no specific ASN/ISP is identified for this incident.
- **The mechanism** — we cannot state whether this was DNS tampering, TLS/SNI reset, HTTP blockpage, throttling, or an infrastructure outage.
- **Sub-national scope** — measurement is aggregated at the country level; we cannot localize to a province, city, or network segment.
- **Independent corroboration** — this rests on a single source; treat it as a single-source signal, not a multi-source confirmation.
