Lag so bad

My user id is 40/42003986. I play on USA East. I am an elite lvl 19, my elite points are:
80'054'284 / 92'118'218.

My problem:
I cannot play at night due to horrible lag. I log on many mornings around 6:00 am est. I have no problems whatsoever with lag in the mornings from 6:00 am until 1:00 - 2:00 pm est. From 2:00 pm - 7:00 pm the game becomes somewhat lagging but is tolerable.
At night however starting from 7:00 - 8:00 pm est until midnight, I simply cannot play the game. My ship freezes on the seachart and will stay frozen for 3-5 minutes at a time. Then it will unfreeze and I can pick up 1-3 shineys or travel 1/2 across the map, then my ship freezes again. I click bottom left and my ship goes bottom right.
I do not believe the problem is my computer. I have a new gaming computer that works wonderfully. The problem is not my cache. I do clear it often and this does not improve my ships performance. I even play on Google's incognito mode so there is no cache.
I play on several different browsers. I use Google Chrome, Internet Explorer, and Diglo. With all three browsers I experience the same lag.

My Question/s:
1. Is there another browser that may work better than the ones I am currently using?
2. Is there something that I need to change in the settings on my sea chart screen?
Under graphics I run view port at: maximum. Display details I have on: low.
Maximum FPS: I have it maxed out. Smooth map scrolling and faster map changes are both checked. Scroll speed is: maxed. Under elements I have all boxes checked except "tool tips".
Under animation all boxes are checked except "boost". Under environment I have no boxes checked.

I suspect that the problem is simply with the game. If that is so then please just say it is and I will no longer try to play, other than in the early am. If there is something that I can change or am doing wrong then please advise. Any help in this matter is greatly appreciated and I thank you in advance for your time.

 

I have the exact same problem, but it's only on USA east, I've never had a problem on uk. been happening since halloween event.

I have a question do you happen to have verizon fios?

 

I do not. I am on att u-verse wireless network. I am located 15-20 minutes north of Atlanta (not sure if maybe location has something to do with it). I am not super tech savy, I know my way around the comp okay but would not be able to check Tracert" on the movement of the packets between clients and server. I am however considering calling the "Geek Squad" to stop by around 8:00 pm and log onto seafight and see if they have a solution. Of course that would dip into my mega hour money this month, but it may have to happen that way lol.

 

Don't bother it's something with bigpoint not sure 100% what it is, but yeah

 

I have complained about this same problem for one and a half months. All they tell me is they don't have a problem on their end or can't duplicate the problem. I hope that with this many players having the same problem they might finally wake up but don't hold your breath. I have tried four different browsers with same results. It's their problem.

 

I will forward all of your information to the appropriate people, and thank you for your feedback. At this time however we are informed that we do not have any major issues that will cause this problem.

This thread will be closed to prevent any discussion occurring, however if we have any further updates or information to offer I will of course reopen this.
