Despite retiring the manufacturing of the Xbox 360 console in 2016, millions of gamers still own one and millions more are able to experience its library through Xbox One’s backwards compatibility program. Microsoft has
server maintenance for April 27th, of which anyone planning to use their Xbox 360 or a backwards compatible game should take note:
On Thursday, April 27 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 maintenance and you can check to see when it’s back up on the official Xbox Live status page
