Source summary

Anomaly rate: 100.0% (21 measurements).

Open incident JSON
Reported anomaly rate
100%

Source-defined signal; not a universal test-failure percentage.

Source measurement count
21

The record’s count can represent aggregate inputs or alerts.

Incident confidence
70.5%

A source score, not certainty of intentional censorship.

Linked evidence has its own count and confidence fields. These quantities are not interchangeable.

Follow the evidence

Evidence unavailable.

Inspect the observation, the upstream claim and why it was linked.

The incident response did not include an evidence array. No evidence count is inferred from that absence.

Upstream claims are attributed to their source. Multiple records or source names do not by themselves establish independent corroboration.

Source-reported corroboration

The source’s corroboration assessment is separate from incident confidence and evidence-link confidence. Inspect its source list, count and description.

No corroboration assessment was supplied.

Declared incident sources: OONI · Voidly ML.

Incident mechanism

No mechanism specified at the incident level.

Individual evidence may carry more specific methods. Those do not automatically describe the entire incident.

Affected domains · 0

Domains named by the source record. Each link opens country-specific OONI measurements; a named domain is not a blanket national-block verdict.

No domains named.

Networks and evidence attribution

ASNs named by this source record: Unavailable.

This aggregate describes fields literally present in linked evidence. It does not identify who caused an event or prove intent.

No evidence-attribution aggregate was supplied.

What this record cannot establish

Measurements alone do not attribute an event to a government, ISP or another actor, and do not establish intent. An outage or anomalous result can have several explanations.

The country label is an aggregation scope. It is not a census of every network, city or service. Regional or ASN fields belong to their individual source evidence and should not be expanded into a national claim.

A confirmed duration is not supplied. The source observation window and evidence timestamps do not prove an exact start and stop of blocking.

Signal definitions, baseline rates and model versions depend on the source. This record does not establish a common baseline or calibrated certainty. Use the source’s specific signal definition and evaluation before interpreting a score.
