Outside the scored OONI profile
Available source records for Chad are shown with their dates and measurement limits. An absent score does not imply unrestricted internet access.
This source branch has no complete scored OONI editorial profile. Current incident and model sources remain independently available.
The original site falls back to the country API and incident records for Chad. No unique OONI editorial narrative is available in that branch.
Editorial text is preserved as source context. Product recommendations do not guarantee unrestricted access. The source tier may differ from the measured score because the two have different definitions.
Score window: Unavailable days. Snapshot fetched . Content first seen . Upstream serve-time . These timestamps do not date the all-time OONI observations.
All-time measurements accumulate from an older source file without an observation window or timestamp. The all-time blocked ratio is not the confidence-shrunk score. Zero counts and absent fields are kept distinct.
All-time measurement archive
No collection date or complete-country coverage claim is attached to this archive. Protocol fields can be incomplete and need not sum to the historical total.

Statuses come from each record; “active” is not inferred from severity or an absent end date. Incident confidence is a source field, not independent certainty that censorship occurred.
This is the source mix in the latest returned incident sample, not independent corroboration of the country score. A record can name multiple sources; the counts can overlap.
Dataset version: 2026.10.03. Malformed rows omitted: 0. All readable returned records appear above; each links to its complete evidence and citation page.
Measurement context
This fallback averages up to 50 incident anomaly fields and sums their source measurement counts. It can combine IODA and other signals; it is not an OONI sample block rate or an independently comparable country score.
Source generated: . This is a source timestamp, not proof that every underlying observation is current.

Use for cross-country RISK RANKING, not precise within-country day-of-shutdown timing.
This forecast scores the ONSET of a new recorded incident, not how censored a country already is. A permanently and stably blocked network generates no new anomaly, so it scores LOW. Measured 2026-07-31: China 0.015 and India 0.023 both rank BELOW Denmark 0.062 — China is probed 30/30 days across 836 domains and has logged nothing for 71 days, while Denmark is probed 2/30 days. A low score here means 'no CHANGE expected', never 'this country is free'. For standing severity use /v1/atlas/score-v2 or the censorship index instead.
Training ROC AUC 0.954 came from a RANDOM stratified split (consecutive country-days in an incident window are near-duplicates, inflating it). No target leakage: features use [date-7,date], label uses [date+1,date+7].

Original display confidence field: 85.0%. The source describes this as fixed in-sample model confidence, not calibrated per-forecast certainty.
Separate multi-horizon model. Each mark is the point estimate; its bar is the source’s 90% conformal interval.
36.4% · 90% interval 26.7%–46.1%

70.0% · 90% interval 20.0%–100.0%
Model: multi-horizon-h-v1. Longer-horizon intervals can be very wide; these estimates do not support precise within-country timing.
Source consistency: within the model’s monotonicity tolerance.
Per-horizon breakdownSource generated: . This is a source timestamp, not proof that every underlying observation is current.
AUC (e.g. 1d ~0.91) OVERSTATES usefulness — per-horizon F1 is much lower (~0.45 at 1d) because shutdown-positive days are rare and the 7/30-day target is a sliding window that is highly autocorrelated day-to-day (a leakage-prone label).
Conformal bands widen sharply at 30d (often ~[0.45, 1.0]) — the 30d point estimate is low-confidence.
Use for cross-country RISK RANKING within the watched panel, NOT precise within-country day-of-shutdown timing. Data-backed for covered countries only (see the 'covered' flag).
This forecast scores the ONSET of a new recorded incident, not how censored a country already is. A permanently and stably blocked network generates no new anomaly, so it scores LOW. Measured 2026-07-31: China 0.015 and India 0.023 both rank BELOW Denmark 0.062 — China is probed 30/30 days across 836 domains and has logged nothing for 71 days, while Denmark is probed 2/30 days. A low score here means 'no CHANGE expected', never 'this country is free'. For standing severity use /v1/atlas/score-v2 or the censorship index instead.
Per-horizon AUC is leave-one-country-out on the SPOTLIGHT (watched) panel, NOT all 130 countries; see /v1/forecast/multi-horizon/info for the per-horizon F1.

Source generated: . This is a source timestamp, not proof that every underlying observation is current.
Similarity here is BEHAVIORAL, not political. Two countries are near each other because they BLOCK in similar ways — comparable method mix, target categories and temporal shape — which does NOT imply comparable governments, laws or intent. A stable democracy with seasonal sports-piracy blocks can sit near an authoritarian state if their measured blocking footprints rhyme. Feature vectors are SPARSE for low-coverage countries (flagged sparse=true, <3 of 5 behavioral feature families populated) — their neighbors are dominated by regime/continent/cohort one-hots and should be read with low confidence. The 2D graph projection (UMAP or PCA) compresses a 32-dimensional space to 2 and loses information — use the cosine `neighbors` list, not pixel distance in the projection, for any quantitative claim.

Use the recent records and their original sources to investigate a particular restriction. Disruption alone does not establish intentional censorship.
There is no scored OONI editorial profile in this source branch. Use the dated incident evidence and domain checks for specific services.
