Unbearable lag in USA and Australia Server

I tried joining several games by using the AlterIW Server List. I joined a USA server, Team Deathmatch Rust Map, and I got 500 ping. Damn, that was high. The whole match was full of spike. Then, I tried to join an Australian server and the lag got worst with 600 ping. Anyway, its actually a good thing since I no longer have to wait to search for available games using the fucked up match-making system.
