Load Balancing - Load Balancing now supports regional health

<p>Cloudflare Load Balancing now supports regional health. Each Cloudflare region can make an independent health decision for a pool. When pool reachability differs by region, traffic can avoid an unreachable pool without removing it from service elsewhere.</p> <p>Configure regional health with the <code>health_sources</code> field on a pool. Set it to <code>["regional", "global"]</code> to prefer regional health and use global health when no regional decision is available. Pools without <code>health_sources</code> retain their existing health behavior.</p> <p>Regional health is useful for multi-region deployments and failures that affect specific network paths.</p> <p>For more information, refer to <a href="https://developers.cloudflare.com/load-balancing/understand-basics/regional-health/">Regional health</a>.</p>
