This blog post is a follow-up on the outage that occurred on September 8th. Just before 8:00 PM PDT that day, we became aware of a Domain Name Service (DNS) issue that was causing a service interruption for some some Microsoft services, including Windows Live services such as Hotmail and SkyDrive. No customer data was lost or compromised during this outage. The team has investigated the root cause and has taken immediate steps to improve.
