[UPDATE 7:34 PM EDT] "Purchase and Content Usage" on Xbox Live for Xbox 360 remains "limited," but the rest of the core services are back up and running

The original story is below.

Xbox Live for Xbox 360 is currently facing a number of issues.

A service alert posted on Microsoft's website explains that Purchase and Content Usage and Social and Gaming are "limited." Earlier today, core services like signing-in were affected, but those problems have since been fixed.

"Are you having a tough time matchmaking or using the Smartglass application? We're hard at work right now trying to get things back to normal," Microsoft said. "Thanks for your patience!"

Xbox Live for Xbox One is not affected.

The issues for Xbox Live on Xbox 360 today come on the same day that Grand Theft Auto V introduced the long-awaited online Heists mode. It is unclear, however, if the Xbox Live downtime and the release of Heists are in any way connected.

"Microsoft is aware of an issue affecting access to some Xbox 360 services. We are working to restore full access to these services as quickly as possible," a representative said.

GTA Online Heists, too, are struggling today.
