Microsoft's status website for many of its online services is reporting a disruption to normal operations to many of its online services as of about 5:35 PT/ 8:35 EST. Included in the disruption to normal operations are Hotmail, Outlook.com, Calendar, and Skydrive.
An interesting note on the calendar issue is that it states that Microsoft is performing maintenance on the product which doesn't really mean its an outage (assuming it was scheduled). We hope, but have no information about, is that Microsoft is finally updating the aged calendar for Outlook.com users. As of about 9:15PM, the calendar issue has been resolved but the old design is still present.
The other issues related to Skydrive, Hotmail and Outlook.com appear to be more serious with each service having issues that affect the end user experience that is not related to on-going maintenance.
While Microsoft's online services have traditionally had exceptional uptime, this is the second disruption to the service with the last outage occurring on February 1st.
[Updates] As of 9:07PM, Skydrive service has been restored | As of about 9:15PM, the calendar issue has been resolved. | As of about 10:20AM on 3.13, all services appear to be back up and running.
Thanks for all the tips guys, we love you too!
