“The playable Living Story content will start appearing tomorrow (January 29) at around noon Pacific Time in Wayfarer Foothills. You will see refugees requiring your assistance along the path, around Breakneck Pass.
Later on that day, there will be events in Diessa Plateau. You’ll be sent an in-game mail letting you know about the events in Diessa Plateau. If you’re already logged in when that happens, you need to change maps to receive that message.”

So the main events aren’t meant to have started yet, at least not specifically.
