Need help, ping problems

3 out of 7 last matches i got 600 ping
I double checked internet conection - all good, played on every non faceit server - all good.
On avarage i got 100 ping (living in Kazakhstan :/) if its German faceit server or 90 ping on Netherlands.
But last 2 days it was terrible, Im not sure if its about internet connection or my client or its about faceit servers. Please help someone because I cant play properly :pray:
