Where connectivity, BGP routing, and undersea cables go dark.
Correlates Georgia Tech IODA control-plane BGP and active-probing drops with OONI censorship telemetry, a hand-compiled register of submarine cable corridors, and suite tips (Elements earthquakes and volcanoes; Wake AIS once it is live) to tell apart domestic policy shutdowns from physical cable cuts.

Submarine Cable Corridor Alerts & Chokepoint Registry
Warning problem BO-WP-2: triggered when ≥2 countries sharing a submarine corridor drop ≥20%, or when a drop co-occurs with a BO-IND-5 tip (≤50 km).

Active BGP & Probing Outages (IODA)
Median during the event against the median of the 7 days before it, per IODA signal (BGP, active probing, darknet). BO-IND-1: ≥25% for ≥30 min. BO-IND-4: one signal drops while BGP holds. A drop is called a likely shutdown only when OONI blocking (BO-IND-3) is present in the same country; on its own it fits a power or physical fault as well, so it is recorded as a measurement.
Application-Layer Censorship (OONI)
Confirmed blocking + anomaly share of all OONI measurements over 7 days, all tests together (BO-IND-3: ≥15% over ≥50 measurements). A fixed threshold, not a change from baseline: some countries sit above it every day.
Suite Tips (Elements, Wake, Vigil)
Interests BO-INT-1 (earthquakes, volcanoes), BO-INT-2 (AIS loitering or anchor drag; Wake is not live yet) and BO-INT-3 (attacks on telecom carriers). A tip counts toward a cable-fault call (BO-IND-5) only when its own coordinates fall within 50 km of a corridor point; tips naming an outage country are shown as context and do not change any likelihood.
