Scale globally using Regional Routing with Tailscale

Tailscale has introduced Regional Routing, a feature designed to enhance scalability and reliability for businesses with global operations by routing and balancing traffic through the nearest available infrastructure. This new capability allows organizations to manage overlapping app connectors and subnet routers within regions mapped to Tailscale's DERP regions, ensuring high availability and improved performance. Regional Routing supports various scaling methods, including global geo-steering, in-region load balancing, and failover, offering flexibility to meet diverse business needs. Clients connect to the nearest DERP server and are directed to the closest available connector, with ongoing re-evaluation for optimal resource access. The feature includes in-region load balancing, which distributes traffic evenly among multiple connectors, and failover options for redundancy, enhancing global high availability without requiring Tailscale-owned infrastructure. Previously exclusive to higher-tier plans, failover is now accessible to users across all plan levels.
