Destiny will be down on Thursday, November 13th, for a few hours so that Bungie can prepare to apply a series of updates to the game itself in preparation for the upcoming December expansion, The Dark Below.
The official Bungie blog post states:
“This totally planned service outage will enable us to prepare for the arrival of a series of updates planned for the next few weeks. During this time, you’ll be unable to play Destiny. We’re sorry about the interruption, but it’s for the greater good.”
The maintenance window will start at around 8am Pacific time till noon. The blog post also states that “once services are restored, your experience as a player will be unchanged” and that “you won’t need to download or install a new batch of content” once the changes have been applied.
Destiny’s next expansion, The Dark Below, will arrive for all platforms on 9th December.
