Hey, fellow SEA players here and i am in Indonesia
I play on Proudmoore (LA/US West) with ~200ms perfectly fine… until 2 weeks ago. Just few hours after weekly reset.
Everytime i got stuck in loading screen, or have super high world latency. I check which server i connected to, by looking at the outbound connection using network utilities tool (on Linux, i uses TCPdump with only WoW active)
What i do is that, i note down the IP address that show up
Blizzard server will always be: 64.224.xx.xxx so i traceroute to them to check
Here are list of server i have issue with (so far)

All have similar issue: Packet Loss, and this seems to only happen in US servers.
What interesting is, there are several US serves that i don’t have issue with, and plays like i would normally do, and some servers work fine after i alt f4 and relog (it’s in an instance, so server stay the same which is the leader’s, unlike world server)
I would say aroun ~20% of the time, i won’t have issue.
Here’s an example of good US server, 64.224.30.149:https://imgur.com/JTCicgK
These are few are far between, the one i notes down are only this server, but i think there’s 2-3 more. (because i don’t have issue with said server, i didn’t traceroute it)
Now to check if this Packet Loss is on my end, i tested with other server that is not World of Warcraft. And i have 0 packet loss.
The last domestic node for me is 180.240.190.101, the node after that went International, specifically eqix-ix-la1.blizzard.com (so at that point, my ISP has ZERO control)

As you can see, packet loss / unstable connection only happen in US servers. Even VPN often struggle with it.
THIS ISSUE IS NOT ON YOUR END
my speculation is that, because our connection is unstable, we constantly tries to reconnect with the game server, and we might have tripped Blizzard anti DDOS measure to limit rate our connections.
This in-turn causes us to be unable to reconnect quickly enough that causes massive desync with the server (huge world latency, but low home latency) or you’re unable to connect altogether (or dc’d, but if you’re in the game, you mostly fine)
