Every time i've tried to play D3 today, i've been experiencing major lag issues. My latency will be around 100 and then randomly spike to 4k, then back down to ~500, and level out again around 120 or so. I died quite a few times trying to do key runs, and just gave up because the latency spikes are just terrible.

I'm not experiencing this on WoW or any other game i've played today. JUST Diablo.
