BioWare will be taking down the servers tomorrow to deploy patch 2.1.1. It’s not 100% sure yet though, as the devs are struggling with some issues. Eric Musco posted this on the official forums:
I wanted to give an update so I wasn’t leaving you guys hanging! Right now we look entirely on track to publish Game Update 2.1.1 tomorrow morning with maintenance. Assuming no other speed bumps jump out, Amber will be posting maintenance messaging and patch notes later today.
Thanks everyone! Should anything change I will let you know but otherwise we are good to go for tomorrow.
