Same here (and also in the northeast.) Known issue, and there are a few threads already on this forum. I've put in a support ticket, sent them all the information they wanted, and they told me they're working on it. Not noticing any difference here. I got on and switched to the European servers, where I can play without incident.
Except for today's Zushen mission. It keeps putting me back into the US districts, which means I get stuck at the loading screen.
