Latency problem with Singapore

Have been playing the "Settler league" since launch and stop after a month or 2 with no problem. When trying to play the "Settler league 2.0" then the latency from 70-80 shoot up to 250-500 ping randomly, also from the main menu of the game where the server and ping shows 70-80 but change during in-game. No problem with other games but was keen to try the 2.0 league.

Here is the winMTR 0.92

Want some answers to this question and there is no problem to ISP.

Same issue here. I can't believe the whole SEA area only has 1 server that doesn't work and GGG hasn't even said anything about it going back more than a year.

Experiencing this problem as well on AU server

Update:
Strangely enough while trying to connect "Auckland(NZ)" server at 196ms but its stable at 190 to 200 while Singapore server is at 70-80ms in town or hub and when I try to enter different areas then it spiked to 200 - 500ms.
Just seeing this means there is something wrong coming from the "Singapore" server. I even tried pinging to Singapore from different site other the GGG server seems OK expect for the "GGG - Singapore server side".

Tried using WinMTR again and there is small improvement from the previous WinMTR link doc. Here the latest second WinMTR link below:
