Me and a buddy both have been experiencing this for a while. We assumed it was still DDOS attacks. We've been having lag that lasts 1 to 2 second frequently, 10 second DCs occasionally, and at least 1 disconnect a night. We can't do any serious content with this amount of lag and DCs.

We are also in the Phoenix Metro area and use the ISP COX. I will try to call them tomorrow. I hope SE try's to leverage their voice in this matter if they can.
