Microsoft teaches you how to inspire confidence in the cloud

For the better part of yesterday a good portion of Microsoft's Azure was down across the globe, with no geographic location left unaffected.  Azure is not only Microsoft's cloud storage service but also handles authentication for Office 365 and hosts the Exchange servers used by the new office suite.  Thankfully it was not a complete outage but the scope of the problem is quite worrisome, Microsoft has always claimed that Azure is partitioned geographically to prevent these types of global outages; their FTP service also failed during this outage adding credence to the lack of partitioning and possibility of cascading failures.  A failure of this magnitude on a business critical service is quite worrying but allowed The Register to give us a new term, "Blue Sky of Death".

"Microsoft's Windows Azure cloud was hit by a worldwide partial compute outage today, calling into question how effectively Redmond has partitioned its service.

The problems emerged at 2.35AM UTC, and were still ongoing as of 10.20PM UTC the same day, according to the company's service dashboard."
