Source summary

IODA detected significant connectivity drop in Angola. 16 critical alerts recorded.

Open incident JSON
Reported anomaly rate
24%

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

Source measurement count
16

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

Incident confidence
75%

A source score, not certainty of intentional censorship.

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

Each point is a linked record. Horizontal position shows observation time; stacking separates nearby points. The full records below provide the values. This is not a measured outage-duration chart.

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.

Declared incident sources: IODA.

This record does not list two distinct sources. Treat it as a single-source or uncorroborated record.

Scope and attribution

What the record names.

Methodology

Affected services

No services named.

Incident mechanism

Infrastructure outage

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: None listed.

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

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.

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.
