My thoughts are that there is some issues going on for some backbones at present, I know some just want to just blame the game servers, but without pathpings etc it is just a claim.
Have a look at the below thread, for Slugwarts yesterday I would say he found a good path to the servers by trying a different ISP. http://www.swtor.com/community/showt...=525189&page=4
For those that claim all other games are good if you think this is just this game at present, how do you explain threads like http://us.battle.net/d3/en/forum/topic/7864606397
and the tone is just like people here.
The internet can and does have ongoing issues and can happen anytime, most are fixed in 24 hours but those that aren't means it is likely not a simple fix, your ISP and Biowares end are very small parts of the internet.
This is not to say server issues do not occur, they can, but when they do you have hundreds of people posting here at once, this can also occur when it is just a major internet issue as this affects the majority of people playing on a particular region server.
Is it frustrating, yes it certainly is, is it your ISP or biowares fault, most likely not.
