Azure Active Directory B2C Service Goes Up to 'Four Nines'

Microsoft recently announced an upcoming increase in the Azure Active Directory B2C service-level agreement (SLA).

According to a Wednesday announcement, the Azure AD B2C (Business to Consumer) service will get bumped up to "four nines" (99.99 percent) in SLA uptime assurance starting on May 25.

This increase in SLA support will just apply to user traffic, though, and Microsoft is planning to alter its SLA to reflect that change. Here's how that notion was expressed in the announcement:

This [change in the Azure AD B2C SLA] 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.

Back in mid-December, Microsoft had said it would bump up the SLA to 99.99 percent for its Azure AD service, starting on April 1. However, it indicated back then that the SLA would get altered and it would just apply to end user access, and not to administrative activities that might get interrupted by Azure AD downtime. 

That circumstance also seems to be the case for the 99.99 percent SLA for the Azure AD B2C service that's coming in May.
