MSN Messenger falters for more than 10 million users

Microsoft said Thursday that a hardware failure had crippled parts of its instant messaging service, cutting off all or part of the service to nearly one third of its customers around the world.

MSN Messenger is Microsoft's free instant messaging software and is used by 31.9 million people worldwide, according to research firm Jupiter Media Metrix Inc. As early as Wednesday some users reported being unable to log on to the system, or losing access to their personal contacts, or "buddy" list. The service was still unavailable to many users as of Thursday afternoon.

"In this case, an extremely rare set of circumstances occurred when one of our database servers had a disk controller fail," Sarah Lefko, MSN Product Manager, said in a statement. "The backup for this controller also had an error occur which resulted in it not being able to fix this issue immediately, resulting in the current situation."

The company refuted reports that the outage was related to its Passport authentication service, a service that its e-mail customers use to log on to Microsoft services and other Web sites. "The issue is hardware-related and MSN is now working closely with our vendors and taking appropriate steps on the back-end to resolve the issue and restore service to all MSN users worldwide," Lefko said.

Microsoft has said it will include a more advanced version of the Messenger product with its new operating system, Windows XP, which is set to be released on Oct. 25. Called Windows Messenger, the application will come with text, video and audio messaging capabilities.

While many users have lost access to their buddy lists, Microsoft said the information has not been lost. "When the issue is resolved customers' personal buddy lists will be restored," Lefko said in the statement. "There is no need for users to take any action to restore their personal buddy lists."

Microsoft would not speculate on when the hardware problems would be fixed, noting only that it is "taking action to resolve the issue as soon as possible."

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
