Yemen · June 1, 2026 · 11 days
OONI detected 3 days of elevated network interference averaging 50.0% anomaly rate.
Evidence
50%
Anomaly Rate
3
Measurements
69%
Confidence
What This Means
50% of tests showed anomalies, above the typical 1-3% baseline. This suggests potential network interference.

What we cannot say
- Who caused it — measurement data alone does not attribute this 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, an 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.
