Now with more DERP

Tailscale has enhanced its network by adding nine new DERP relay server locations globally, including cities like Amsterdam, Denver, and Hong Kong, to improve the reliability and speed of direct connections between clients. These servers are part of a global infrastructure that helps devices establish connections even in challenging network environments by using DISCO packets for communication and providing alternative paths when direct connections are not feasible. The addition of more DERP locations and the expansion of existing servers aim to reduce latency and improve throughput by ensuring devices are closer to a relay, which in turn lightens the load on current servers and enhances user experience. Users can utilize tools like "tailscale ping" and "tailscale netcheck --verbose" to identify the nearest DERP server and assess their connection path.
