# Sustained censorship in CR (2026-11)

**Country:** 🇨🇷 Costa Rica (CR)
**Date:** 2026-11-03
**Type:** Censorship
**Severity:** CRITICAL
**Status:** confirmed

## Summary

OONI detected 4 days of elevated network interference averaging 70.0% anomaly rate.

## Metrics

- Confidence: 72%
- Measurements (stored incident count; not the qualifying evidence count): 4
- Anomaly Rate: 70.0%

## Evidence

- **OONI** (measurement): OONI tor: 4 anomaly + 0 confirmed / 5 nonfailed measurements (80.0% blocked; 0 failed)
  - Observed: 2026-11-04
  - Confidence: 82%
  - [OONI Explorer filtered results (not one measurement)](https://explorer.ooni.org/search?probe_cc=CR&test_name=tor&since=2026-11-04&until=2026-11-05)
- **OONI** (measurement): OONI tor: 2 anomaly + 0 confirmed / 4 nonfailed measurements (50.0% blocked; 0 failed)
  - Observed: 2026-11-04
  - Confidence: 70%
  - [OONI Explorer filtered results (not one measurement)](https://explorer.ooni.org/search?probe_cc=CR&test_name=tor&since=2026-11-04&until=2026-11-05)
- **OONI** (measurement): OONI tor: 1 anomaly + 0 confirmed / 1 nonfailed measurements (100.0% blocked; 0 failed)
  - Observed: 2026-11-03
  - 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.
- **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.
