Latency issues on Romania RDS

Hello,

I have latency issues when i am playing Starcraft.( Romania )
In the past i had no issues , this started few months ago.I use the same provider as i did in the past , i have optic fiber with gigabit plan , so it is not a bandwidth issue. I have 2 laptops( mac and windows ), same problem on both.
Tried to bypass router, and use cable directly, issue persists.
Any idea?
PS: I am using the free version of Starcraft. If i buy Remastered, will fix this issue?I don’t mind buying it , but if i have the same issue is useless.

Thanks,
Cristian
