Yeah... as a person who is currently in Asia.
LA to Asia is crap/a lie. I'm behind a "business grade network" and... well... It definitely sucks. Internally (within the country) the network is awesome, full Gbit and everything. But once your traffic takes a step (or... I guess just leaves?) Asia it goes to... well... crap.
Staying on topic though. People I've used in LA area are BuyVM (LV -> LAX), Hostigation (Quadranet), BlueVM (doesn't have IPv6 though so I guess it doesn't apply to this) (ColoCrossing/Quadranet), NodeDeploy (Unfortunately they shutdown/removed their LA location).
