So around November 30th my ping went from an extremely consistent 79 ping to an extremely inconsistent 70-200 ping overnight. I'm in NA, near San Francisco, and my ISP is AT&T. None of the people in my house are doing anything they haven't before. I'm on a wired connection.
So what the hell is happening? It's been this way for a couple weeks and having ping double what it was before is driving me insane.
