Same problems for me, I have traced the problem to be a company called level3, that is some sort of a telecommunication company through which the swtor data/connection goes through. They are giving me thousands of server lag everywhere, Strongholds, every planet, every location, every character, on The Progenitor EU server. It's making my game totally unplayable, DC'ing all the time, yet every single other internet using program/game works perfectly on the side. It has -nothing- to do with my computer/connection. I have contacted BW customer service for this, yet they always answer with the same automatic reply of ''Try to use our troubleshooting'', which I've tried, every single suggestion, nothing helped, its SO frustrating, since I JUST resubbed, I'm paying for their game that I'm not even able to play anymore. I contacted level3 through their facebook page, and they answered, asked me to contact my own ISP (Internet Service Provider), I did, and they said they arent able to help. How is this fair for a paying customer of Bioware/EA?
Though the issue might be where your traffic enters Level 3's networks, that doesn't mean that the problem is their network. They have a couple of articles about this that some of you might find informative:

Of course your ISP is going to say that they're the problem. Why wouldn't they? But the problem is quite a bit more complex than that. Be persistent with your ISP. They do, in fact, have the power to remedy the problem, but a tier 1 tech won't know that, and is likely to just brush you off.
There might be throttling going on, but it's going to be by your ISP rather than by Level 3. It's not the first time that ISPs have throttled traffic as part of a dispute.
