urgent question about slippage while using vps

 
hi, i'm copying a signal for a week and i am using a vps as well. in the beginning the slippage was non existant but since yesterday i'm having a slippage of over 8 points, sometimes 4 points, i didn't change anything, why is that? is my broker on purpose causing slippage? or what can it be?

Contact the signal provider for advise, this is an issue between your brokers.

 
No one can figure out why. when i subscribed to the signal, my broker server was in the top green slippage section of the signal and now it fell to yellow and sometimes orange. is it normal for the servers on slippage page keep changing latency?
