EDIT3: Xbox 360 is affected too, Both Social and multiplayer services are affected, this is an XBOX Live issue not specific to destiny, Neverwinter nights seems to be unaffected (they probably don't use XBL code extensively). Please bump to raise awareness and to consolidate the information into one place. Unable to login. Don't panic if you get the "Your permissions may have been changed" error this is a generic error message intended to cover both loss of server connectivity and possible bans from an activity, if you are a normal player (ie don't cheat) you have nothing to worry about.
