# Sustained censorship in AT (2026-10)

**Country:** 🇦🇹 Austria (AT)
**Date:** 2026-10-16
**Type:** Censorship
**Severity:** CRITICAL
**Status:** confirmed

## Summary

OONI detected 3 days of elevated network interference averaging 65.5% anomaly rate.

## Metrics

- Confidence: 69%
- Measurements (stored incident count; not the qualifying evidence count): 3
- Anomaly Rate: 65.5%

## Evidence

- **OONI** (measurement): OONI http_invalid_request_line: 5 anomaly + 0 confirmed / 7 nonfailed measurements (71.4% blocked; 0 failed)
  - Observed: 2026-10-17
  - Confidence: 79%
  - [OONI Explorer filtered results (not one measurement)](https://explorer.ooni.org/search?probe_cc=AT&test_name=http_invalid_request_line&since=2026-10-17&until=2026-10-18)
- **OONI** (measurement): OONI http_header_field_manipulation: 4 anomaly + 0 confirmed / 8 nonfailed measurements (50.0% blocked; 0 failed)
  - Observed: 2026-10-17
  - Confidence: 70%

- **OONI** (measurement): OONI http_header_field_manipulation: 3 anomaly + 0 confirmed / 4 nonfailed measurements (75.0% blocked; 0 failed)
  - Observed: 2026-10-16

## 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.
