FINDING · EVALUATION
Circumvention activity varied strongly by geographic proximity to the crisis: Hubei province, the epicenter, saw Twitter volume double relative to pre-lockdown baseline and sustain that doubling 30 days after the crisis, while mobility decreases from Baidu location data correlated with Twitter user increases across provinces — but two weeks after lockdown, the elevated Twitter usage could no longer be explained by mobility restrictions or New Year seasonality, indicating crisis-induced circumvention becomes self-sustaining.

Implications
- Deploy additional proxy capacity regionally near crisis epicenters — geographically targeted demand spikes can double usage in affected areas while other regions see smaller increases, making regional load balancing more effective than uniform scaling.
- Circumvention habits formed during crises persist even after the precipitating event ends; this argues for long-lived proxy infrastructure rather than ephemeral surge capacity that is decommissioned post-crisis.
