Hi@矢野 尭生

Thank you for reaching us!

I understand your query about data replication in Azure AD B2C.

To answer your question Yes, Azure AD B2C replicates user data across multiple datacenters within the same region to ensure high availability and disaster recovery readiness. This helps ensure that your user data is always accessible and protected in the event of an outage or other interruption.

To answer your other question, Azure Active Directory B2C (Azure AD B2C) does not replicate data across multiple regions by default, because it can add latency to operations When data is replicated across multiple regions.

I hope this answer helps! If you have any further questions, please feel free to ask.
