**Country:** 🇱🇻 Latvia (LV)
**Date:** 2026-10-09
**Type:** Censorship
**Severity:** CRITICAL
**Status:** confirmed

## Summary

OONI detected 6 days of elevated network interference averaging 69.0% anomaly rate.

## Metrics

- Confidence: 72%
- Measurements (stored incident count; not the qualifying evidence count): 6
- Anomaly Rate: 69.0%

## 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.
- **A confirmed duration** — we report the observation window, not a verified start/stop of any block.
- **Sub-national scope** — measurement is aggregated at the country level; we cannot localize to a province, city, or network segment.
- **Independent corroboration** — fewer than two source labels appear in qualifying linked evidence; stored incident source labels may include quarantined OONI observations.

## Data Sources

ooni

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.
