Source summary

CenAlert detected interference. Impact: 1.0. Reported by: HTTP blocking (tcp-reset): 5/5 probes blocked (100.0%) for bbc.com.

Open incident JSON
Reported anomaly rate
1%

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

Source measurement count
1

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

Incident confidence
65%

A source score, not certainty of intentional censorship.

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

5 linked records.

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

Qualifying linked evidence sources: Censored Planet (5). Historical incident source labels may include quarantined observations and are not detection evidence by themselves.

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 (historical metadata): Censored Planet.

Qualifying linked evidence sources: Censored Planet (5).

Fewer than two qualifying linked source labels are present. Stored incident labels may include quarantined OONI observations and do not establish corroboration.

Scope and attribution

What the record names.

Methodology

Affected services

No services named.

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: None listed.

This aggregate describes fields literally present in qualifying 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.

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.

Read incident JSON

Read the published record and its observation dates. A fresh response does not mean a new measurement or confirm a current restriction.

MCP and curl examples

Claim assessment is on hold. While the public incident projection is under review, the unified MCP service may answer verify_claim with an insufficient-evidence response. The example below is a request, not a verified conclusion.

Unified MCP endpoint: https://api.voidly.ai/mcp. Use the request in an initialized MCP client. Nothing runs on this page.

The curl command reads the published incident record; it does not call verify_claim or test a network connection.
