I am pretty sure you dont care, but I reinstalled and was intending on subbing for the bonuses to gathering. The lag is, well lagtastic.
I run a server and host a game server of my own. Granted it is not a mmo, and doesnt require the potential size you need, but I really doubt you are being ddosed, so it seems like you have either a problem with your host providing your internet, a damaged ethernet cord, your server and or isp host is under a massive storm, thus providing poor quality service or your using the same hardware from when you set the servers up, and they are showing serious signs of wear and tear.
Eitherway, your inability to control this issue lost my sale. Ill chck back in a month or 2 and see if you guys got around to addressing the concerns of your consumers.
