Competitive benchmark: Voidly vs Cloudflare Radar / Access Now / NetBlocks (20 landmark events)

Hand-curated lead/lag comparison across 20 landmark shutdown events (2019-2026): Mahsa Amini, Bangladesh quota protests, Brazil X/Twitter, Venezuela election, Kenya finance bill, Sudan coup, Myanmar coup, Uganda election, Cuba 2021, Kazakhstan 2022, Kashmir 552-day blackout, Bloody November, and 8 more. Of 20 events: 1 voidly_led (Lebanon 2026 BGP, +7 days vs Cloudflare via forecast-threshold-cross — our only true live-detection claim), 0 lagged, 0 tied, 19 backfilled (Voidly DB row from historical OONI ingestion, NOT a live pipeline detection — these do NOT support a real-time lead claim). Honest caveats baked in: we measure publication-vs-publication only (not internal detection at competing orgs), curated list is intentionally biased toward landmark events (use /v1/atlas/prediction-track-record for the non-cherry-picked sample), Cloudflare Radar's public event browser doesn't cover pre-2021 events.
