On Thursday the services of Microsoft's cloud-based Windows Live services took a beating when a Domain Name Service, or a DNS issue rendered the service inaccessible, globally. According to a blog post on Windows Live, for several hours users of Microsoft's Hotmail, Office365 and SkyDrive could not gain access to their accounts.
The following is the course of the updates chronologically:
UPDATE 9:45 PM PT:
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.
UPDATE 11:02 PM PT:
We're aware of reports including the comments posted below that some customers still are seeing issues. We are working on propagating the DNS configuration changes and so it will take some time to restore service to everyone. Again we appreciate your patience.
UPDATE 11:49 PM PT:
We have completed propagating our DNS configuration changes around the world, and have restored service for most customers. Depending on your location you may still experience issues over the next 30 minutes as the changes make their way through the network. Thank you for your patience as we have worked to address these issues.
