7-day shutdown forecast · calibrated

Sudan — 4% current-regime risk

Calibrated via isotonic refit on 810 live outcomes (2026-05-20). See calibration drift → · Sudan country profile →

The Voidly Sentinel model scores Sudan at a peak 3.9% shutdown-risk level over the next 7 days, highest on day 6 (Wed, Aug 19). Average across the window: 3%. This is a current-regime risk reading, not a prediction that a new shutdown will start — see the scope note below.

Honest scope: this is a current-regime risk signal, not a shutdown-onset predictor. It reliably flags countries already in a sustained blocking regime; on the days a new shutdown actually begins its skill is at/below chance (transition-row AUC ~0.33). Why →

90% conformal interval: [0%, 39%] — empirical coverage 90.7% (target 90%).

Honest caveats

What this forecast is — and is not

The 7-day forecast is a current-regime risk signal: it reliably tells you which countries are currently in a sustained internet-blocking regime. It is not a shutdown-onset predictor — it does not reliably call a new shutdown before it happens.

On an honest forward-temporal split (train on the past, test only on the strictly-future window) the production model scores AUC 0.589 on its raw label — near chance.
The label target_7day is a 7-day sliding window, so it is 98.9% autocorrelated day-to-day. A trivial predict-yesterday baseline scores AUC 0.957 — high numbers here mean “what is blocked stays blocked,” not predictive skill.
On the rows where a shutdown actually begins (transitions) the forecast scores AUC ~0.33 — below chance.

Use it to see where censorship is entrenched today and to read the SHAP drivers + conformal interval — not as an early-warning siren. Read the full honest re-evaluation →

Calibration was refit on 2026-05-20 on 810 live outcomes — it's good for the 30 watched censoring countries but will drift if the world changes. Nightly recalibration runs at 04:30 UTC.
A 70% forecast doesn't mean a shutdown is guaranteed; a 20% forecast doesn't mean it's safe. The 90% conformal interval is the honest uncertainty band.
