CrossFire EU is the only game lagging?

[-[Nero..x3]

As the title says, since 2 days this problem started and it's that I have my ping unusually 300-5000 and only in CrossFire EU, in any other game the ping is fine (80-100) and I also had good ping since the 2 days and was playing CrossFire without any problems, but now Idk what's happening.
P.S: It lags on X-Trap, HGWC, Steps (1-4) & in-game playing.

Ping is usually connected with your connection between the game servers and your computer, if you're having no problem on other games you might want to try another server.

No offense, did you read carefully?
