Cross-correlation does NOT imply causation. Significant lead/lag pairs may reflect (a) one country influencing another, (b) shared regional or geopolitical drivers (elections, sanctions, fiber routes), or (c) downstream measurement effects from overlapping ISP infrastructure. lag=0 (simultaneous) is intentionally excluded -- see /atlas/correlation-matrix for that case. With 50 countries and 31 lags evaluated per pair, the raw p-values overstate significance; we apply Benjamini-Hochberg FDR control at alpha=0.05 and require |r| >= 0.4. Counts come from the citable-censorship subset (incident_type IN censorship/mixed) -- IODA disruption rows are excluded since they include fiber cuts / weather / DDoS.
