A handful of Microsoft's online services, including Xbox.com, appear to be experiencing a global outage Thursday afternoon.

The outage, which Twitter users began reporting around 3 p.m., also affected Outlook.com and Office365.com, other online services hosted by Microsoft's Azure cloud computing service. Error messages generated during attempts to visit the sites indicated it might be a DNS issue.

The degree to which sites were affected appears to be varied. Some users also reported that TechNet, MSDN, and even Microsoft.com were offline as well, but those sites were available to this reporter. At one point Thursday afternoon, every region around the world was experiencing "a full service interruption" to its storage services, according to Microsoft's Windows Azure Services Dashboard. But a later update on the dashboard indicated that the services were back to normal operation in each region.

Microsoft said in a tweet it was investigating the cause of the outage and would keep customers updated:

Some services returning now. It's how I can send this tweet now. Patience, please, and sorry for the inconvenience. — Microsoft News (@MSFTnews) November 22, 2013

The Windows Azure storage service suffered a several-hours-long global outage in February when an SSL (Secure Sockets Layer) certificate, used to securely authenticate the service, expired. That outage began on a Friday afternoon and lasted into early the next day.

The outage to Xbox.com comes just hours before the midnight launch of the long-awaited Xbox One, the $499 successor to the Xbox 360 gaming console, which debuted eight years ago. Microsoft is positioning the Xbox One as not just a gaming console but also the hub for living room entertainment.

In a challenge to Amazon's cloud service dominance, Microsoft has been making a push to boost Azure's presence over the past year. The company announced earlier this year that its Linux and Windows Server virtual machines on Windows Azure were available and ready for deployment. These give users a way to run existing Linux and Windows Server apps in the Azure cloud without having to completely rewrite them.

CNET has contacted Microsoft for more information and will update this report when we learn more.

Update, 4:06 p.m. PT to reflect services restored.
