returned to west

Hello, good afternoon, I want to know how the return to the west works. I have 2 accounts of more than 200 m deadlift, that is to say, it is your basic without troops since they are all dead. I have only been off for about 2 weeks, but I do not know how the return thing works, I would like go to a semi-open server where a friend is, is there any way to know when it starts or how do I make it work for me?
