Starlink routing

For the people who have seen their US48 state earth station setups in
person it is pretty normal on the network level. Being colocated with major
inter-city long haul dark fiber DWDM regen sites (Level3 dark fiber path
Seattle to Boise, ID which has a regen hut site in Prosser, WA is a perfect
example) gives them the ability to buy a transport circuit to the nearest
major city/IX point and haul traffic there. I believe they're buying single
100 Gbps waves.
