Same boat here from NZ, comparing trace routes to the server from what it used to be, looks like Telstra have some specific problems and now my ISP has some route in place to avoid Telstra but that involves routing over to Perth, then to Singapore and back into NSW.
It's all pretty much an ISP issue and also doesn't effect everyone as it depends on the routes your ISP use. Someone in my static is sitting at around 270 ping whereas I'm at 130 but some other people in NZ on another ISP it's business as usual with sub-30.
