Crazy Latency in World of Tanks.

[#1]

I don't know what it is as all other games are fine, but in World of Tanks the latency is jumping all over the place.  It;s in a constant dtate of flux, varying second by second from anywhere between 20 and well into the high hundreds.  It's making the game no fun to play at all.  This in on both EU1 and EU2 servers.

You're not the only one

I'm also experiencing this! pings are jumping up to 999 and then timing out.
happens every time after 20 minutes playing the game, did you resolve it?
