Microsoft Cloud Services Outage Appears to be DNS Related [bbc.co.uk]

Millions of Microsoft users were left unable to access some online services overnight because of a major service failure.

Hotmail, Office 365 and Skydrive were among the services affected.

Microsoft was still analysing the cause of the problem on Friday morning, but said it appeared to be related to the internet's DNS address system.

Such a major problem is likely to raise questions about the reliability of cloud computing versus local storage.
