I have Verizon FIOS and live on the east coast. I lag nearly every night during primetime unless I use WTFast. It's probably not your servers, however, it is affecting your game.
From what I understand, there is packet loss concerning how Level 3 routes this data. Last night, many other players reported lag. It seemed to be affecting about 50% of the players in my free company. A wide variety of reports were documented here:

So I ask, what can be done to resolve this? It seems unfair to have to pay an additional monthly fee to play this game. Verizon (or most other ISPs experiencing this) tells you that it's not their problem. However, I suspect it's not SE's problem either. So how does the player resolve this issue? Is SE trying to work with providers to ensure this doesn't happen? Is this similar to the ISPs throttling Netflix? Is there anything we, as a playerbase, can do to help?
