I have a very very very high ping in Counter Strike GO, its going over 900 and normal ping is 144 to 200+ :\ which is literally not playable.
I have made sure that the CSGO application is on trusted through my anti virus and firewall on pc, reading through Forum on reddit i came across that the issue maybe the ISP i am with, which is virgin media and i have looked at multiple forums highlighting issues for high ping spike in CS:GO.
I been getting high ping just recently and before this week i was fine playing the game.
Welcome to the forum and sorry to hear you're having issues with CS:GO. There have been some well known issues with routing to parts of the EU particularly with this game and the trouble appears to be with GTT. So we can see if this is the case or not could you run a traceroute to the server you play on and post the results here for us to take a look?
