DNS Error Downs Several Microsoft Cloud Services

Microsoft has revealed that a DNS error resulted in an outage last Thursday of several Microsoft Live services, including SkyDrive, Hotmail, Office 365 and MSN.

The company has not released further details yet. However, it said that it resolved the problem a few hours after the initial outage. "We have completed propagating our DNS configuration changes around the world, and have restored service for most customers," the company reported in a blog post at 11:49 p.m. PSD.

According to Microsoft, the outage started in Asia-Pacific and then spread to Europe and the Americas. While the initial time of outage has not been disclosed, Microsoft started reporting specific service outages over Twitter around 9:30 p.m. PSD.

However, beating Microsoft to the announcement were multiple online monitoring Web sites, such as, which reported the issue an hour before.

This is the second time in less than a month that Microsoft's online services have suffered an outage. Office 365, CRM Online and SkyDrive went down briefly in mid-August after a hosting issue hit one of Microsoft's North America datacenters. Microsoft responded to the incident by reducing Office 365 customer bills by 25 percent for the month.

Microsoft has given no word if it will offer a discount due to Thursday's outage.
