Just a friendly PSA — Xbox 360, and Xbox 360 games played via Xbox One's backwards compatibility service, will be undergoing server maintenance at the scheduled times on Tuesday, June 20th.
Players who like to get time stamps for their achievements, play online multiplayer games, or are actively completing the Alphabet Challenge
should take note as the announcement cautions that players may be disconnected from Live.
On Tuesday, June 20 between 8:00AM UTC and 10:00AM UTC (4:00AM ET and 6:00AM ET), we will be performing scheduled maintenance that will affect Xbox 360 titles and services.
Please note this maintenance will also impact Xbox 360 backward compatible titles on Xbox One.
All other Xbox One titles and services will not be affected. If you’re playing an Xbox 360 title during the maintenance, you may be disconnected from Xbox Live one or more times.
Everything should return to normal after the completion of the service. If you'd like to see when everything is back up and running, keep up with Xbox Live's downtime on our status page here
