With digital engagement for customers and citizens surging over the past year, resilience and security for our Azure Active Directory (Azure AD) B2C customers has been top of mind.


I am excited to announce that starting May 25, we will update our public service level agreement (SLA) to promise a 99.99% uptime for Azure AD B2C user authentication, which is an improvement from our previous 99.9% SLA.


This builds on our recent announcement of 99.99% uptime for Azure AD user authentication beginning April 1, 2021. In alignment with our updates to the Azure AD SLA, we are revising the Azure AD B2C SLA to include only user authentication and federation in the definition of Azure AD B2C SLA availability.


Thank you for your ongoing trust and partnership.
