Hi @DoZo7,
If you mean in general, the servers for Xbox 360 are up and running. You can check the server status for all platforms at any time from Help.ea.com.
Go to https://help.ea.com/en/dragon-age/dragon-age-inquisition/. There you will see a Server status button. Click on it to unfold the server status window.
What error message did you receive exactly? We can probably have a look at that if it's still happening.
