Description

To improve robustness of static connection tokens, perhaps they should optionally include the derp region's lat/long too, and then if the DERP map changes over time, the client can try the nearest two (Haversine distance probably good enough) to look for the server's public key again

And/or maybe the server should be able to register at two DERP regions.

Research direction

No files or tests are named. Start by tracing static connection-token handling and DERP map usage, then clarify whether nearby-region lookup, dual DERP registration, or both are in scope. Done should be a decided, testable design with clear behavior for changing DERP maps.
