Pretty much doesn't matter about the ISP.
The path to the SWTOR servers trace along this troublesome backbone.
To be fair this really doesn't seem to be a SWTOR based problem. As long as this backbone is not accepting packets the connections issues will continue.
Mine doesn't run through that path. Well It never came up in my traceroute, so I could assume it doesn't go through? Mine follows some 152.179 variants though, so maybe that's what you mean?
