UPDATE: Microsoft has resolved connectivity issues affecting many Xbox Live users, the company has confirmed.
Microsoft has updated its Xbox Live Service status, confirming that connection issues affecting many users have now been resolved.
"Good news, everyone! If you were experiencing difficulties signing in to your Xbox LIVE account, we're excited to tell you that this issue has been fixed," the company said on its Xbox Live site.
Microsoft is working on a fix for Xbox Live connection issues, the company has confirmed.
The Windows firm acknowledged the problem with updates via its official Xbox Live status website.
"Some of our members are experiencing a bit of difficulty when they try and sign in to their Xbox Live accounts," reads the notice.
"We've got your backs! We've got our teams on point and we're working toward a fix as quickly as possible. Thanks so much for your patience."
The outage is said to be affecting users trying to sign into Xbox Live across all its accessible platforms, including Xbox 360, Games for Windows Live, Windows 8, Windows Phone and Xbox.com.
In a separate notice, the firm says "we're aware that our members are having some difficulty accessing video, application, music, and game content on the Xbox console."
It adds, "We've got our top engineers engaged and working diligently to get you back to enjoying all the features that your Xbox has to offer you".
After an unusually long loading process, CVG staff in the US were able to log into Xbox Live via the Xbox 360 console at the time of writing, yet a connection issue appeared to be preventing the console's home screen from loading, and a notice saying that 'Xbox Live content is unavailable' appeared. CVG staff in the UK report they are unable to sign in at all.
