Source summary

IODA detected significant connectivity drop in Iran. 3 critical alerts recorded. CenAlert confirms censorship activity.

Open incident JSON
Reported anomaly rate
23.1%

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

Source measurement count
3

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

Incident confidence
67%

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

11 linked records.

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

Qualifying linked evidence sources: IODA (8) · Censored Planet (3). 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.

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.

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.
