Hey, I also play from Indonesia, I have fiber optics connection.
And usually have about 30-40 ms on any decent singaporian server.
On sea of thieves, the best ping I ever had was about 160 ms with nobody and nothing around. (cause yes the more action and people there is around you the more the latency get unstable and fluctuate very high, up to 300 ms ).
I guess that is a hong kong based server. And usually I set sail alone to have that kind of latency, if I set sail with a full crew I ll be always put on Australian server, and have around 200-250 ms.
I opened a ticket to ask about this situation(also on the official discord), if yes or not singaporian server from azure are being used or not, nobody answered me.
So I am pretty sure they are no singaporian server at the moment. Only Australian server and maybe HK based.
