Destiny is going to be taken offline for several hours in order to prepare it for future updates. The popular first person shooters will be inaccessible starting this Thursday at 8:00 AM Pacific time. (11:00 AM Eastern.) The maintenance is scheduled to end around noon, so it’s about a four hour downtime. Players won’t see any immediate changes after this outage, but infrastructure is being put into place for updates to come in the future.
