High ping after flush dns

Last month my internet was perfect, i have flushed my dns because one single game was crashing, and EA said it was a possibly solution, after the dns flush, my ping was so high, almost 800, after some days my ping was good, then today i have flushed my dns again, i dint know what this was the cause of the problem, my ping is ridiculously high again, can i ""Unflush dns"", i mean, back to my old dns? ( i use it on automatic )

Welcome to the Seven Forums.

Flushing the DNS cache has nothing to do with your ping times.

Every time that you restart your computer, you flush your DNS cache.

DNS cache was probably not the problem with your game.

You should check with your ISP to see if they can fix your connection to the rest of the world.
