Transparent operations from Office 365

Welcome to the place where we share our commitments and information about security, privacy, and compliance.
Robert Dring discusses Office 365 contractual commitments to customers as a cloud service provider
Moving to a cloud service shouldn’t mean losing the ability to know what’s going on. With Office 365, it doesn’t. We aim to be transparent in our operations so you can monitor the state of your service, track issues, and have a historical view of availability.

  • We maintain multiple copies of your data, across datacenters, for redundancy, and we share with you where your data is located and will provide one-month advance notice if we expand the region where your data is stored into a new country.
  • We tell you who has access to your data and under what circumstances.
  • You have 24/7 phone support for critical issues.
  • We have DevOps processes, which means 24/7 escalation to the actual development team to resolve issues that cannot be resolved by operations alone.
  • We conduct a thorough review of all service incidents, regardless of the magnitude of the impact and we share the analysis if your organization is affected.
  • We commit to delivering at least 99.9% uptime with a financially backed guarantee.
