I am having ping issue on all servers below 200+ ping. tested on 2 ISP:

File is included to understand the issue properly:

1)An in-depth description of your issue:

i am getting 250+ ping on Singapore , tiwan , and frankfurt and its been days .
i have 2 different ISP :

1st ISP(100mbps upload/download): and one of them i am getting 250+ ping and only way to get low ping is to keep changing datacenter every time after checking ping in the firing range which takes 1/2 hour. (i get good ping using this ISP in other games like cs , overwatch and warzone 2.0)(image is there in the docx file)

2nd ISP(100mbps upload/2.5mbps download)(going to shutdown in 2 weeks):
i get instant 60 ping as soon as i load in the range. no issue

for both ISP it shows same ping in the datacenter page but different in game. this is happening since the recent update. (1500hrs in game)

2)Your Platform (PC, Xbox, PlayStation, or Nintendo Switch):
==> PC (Steam)(KBM)

3)What you were doing leading up to the issue:
i brought a new ISP as it was providing me more data and speed at reasonable compared to my previous ISP and also it was shutting down.

4)What gamemode (Battle Royale, Arenas, an LTM) you were playing (if applicable)

==> facing it in all gamemode.

5)Any error messages that show up alongside your issue:
no errors were present but packet loss shows up but disappears in an instant.(which was there even before this problem occurred)
