Xbox Live down: Microsoft has confirmed core services are suffering an outage

UPDATE TWO: Fans who reported the first outages on Thursday afternoon are now confirming that Xbox Live's signing in issues on Xbox One look to have been fixed.

But like in most cases, not all features, such as Friends List, are fully operational again.

"I'm back up but I can't get notifications when my friends invite me to parties and stuff," one Xbox One user commented.

Bungie, who have also been monitoring the situation for affected Destiny fans, are also reporting a return to normality.

"We're seeing that Xbox One users can successfully connect to Destiny again, although investigations continue," the studio confirmed on Twitter.

Microsoft say they are still hard at work looking into sign-in issues.

UPDATE ONE: The Xbox Live support team say they have engineers looking into tonight's outage, that has been affecting fans for the past three hours.

"Having troubles signing into Xbox Live? Our teams are on the case," a message reads from Microsoft.

"We can't speculate on a timeframe."

There are currently no other features listed by Microsoft as being affected, although being unable to sign in leaves many of those services out of reach for fans.

The Xbox 360 console has not been listed by Microsoft as being affected and there has been no official explanation on what is causing the latest outage.

DDOS attacks have caused havoc in the past, there is no indication that is the cause of the disruption today, however.
