Frequent Disconnects on South Korean VPN Servers – Is This Common?

I've noticed that South Korean servers consistently perform worse than servers in other regions.

Frequent disconnects, buffering, unstable speeds, and occasional connection failures have become very common for me.

I've already contacted support and tried the recommended troubleshooting steps, but the problem remains.

Is there a specific reason South Korean servers seem to be less reliable than servers in Japan, Singapore, or North America?

I'd like to know if this is a known issue or if other users are experiencing the same thing.
