I'm going to quote Awimboway's post because it is exactly the same problem I have:

"Since the 14th of January I have had persistent 10-20 second lag spikes throughout the day, every day. Some spikes going on for as long as 5 minutes. I don't lose connection during this time but everything just stops then suddenly all happens at once when the lag spike ends (which I am sure is not good for my computer). Is also making the game basically impossible to play, I can just about get my daily quests done each day but if this is something that can't or won't be fixed soon I will have to stop subscribing as paying for something I literally cannot use seems counter-intuitive."

I raised this first with my ISP they have been profiling the line, sent me a new router, micro filters and boosted the line. Both on the old and new router I could see the incoming speed from the provider was and is 19 Mbps. Considering the package I'm on is 20 Mbps maximum, I can't see how this is the ISP's fault. They have no "choke holding" policy in place for my account as I am on their top end package (unless I jump to fibre optic). Lastly, it makes no difference what time I log on the problem is constant.
