Microsoft’s online services briefly go dark


This has not been a good month for the Internet’s core address system: the Domain Name System (DNS). First, there was a man-in-the-middle attack on numerous Web site users caused by a Turkish cracker. Now, according to Microsoft, many of its online services were disabled by a DNS failure.

At first, some people thought this collapse of Office 365, Hotmail, SkyDrive, and other Windows Live programs might be due to problems with Windows Azure cloud or other Windows server problems. It quickly became apparent though that it was a DNS problem.

Microsoft’s senior vice president for Windows Live, Chris Jones, has been keeping users up to date on how the company is handling the problem on the Inside Windows Live blog. By 12:45 AM Eastern time, Jones reported that “We believe we have restored service for all customers at this time. We will continue our investigation into the root cause of these issues and post an update following our investigation. Again we appreciate your patience and apologize for the inconvenience.”

While an easy fix, it wasn’t an instant fix. At that time, Microsoft had only corrected its DNS problem with their master DNS servers.
