Lag sur tous les serveurs.

Bonjour, j'ai un problème depuis 2 ou 3 jours qui fait que quand je me connecte sur n'importe quel serveur j'ai du lag alors que la latence affichée est toujours faible (7ms pour le premium 4 que j'utilise tout le temps). Je me demande donc si ça ne vient pas des serveurs plutôt que de moi. Quand je me déconnecte je n'ai plus de lag. Pour info je suis en Highway to Freedom.
