Fixes tailscale/corp#20971 We added some Warnables for DERP failure situations, but their Text currently spits out the DERP region ID ("10") in the UI, which is super ugly. It would be better to provide the RegionName of the DERP region that is failing. We can do so by storing a reference to the last-known DERP map in the health package whenever we fetch one, and using it when generating the notification text. This way, the following message... > Tailscale could not connect to the relay server '10'. The server might be temporarily unavailable, or your Internet connection might be down. becomes: > Tailscale could not connect to the 'Seattle' relay server. The server might be temporarily unavailable, or your Internet connection might be down. which is a lot more user-friendly. Signed-off-by: Andrea Gottardo <andrea@gottardo.me>
