# Data Residency **emSign** operates its trust services with clearly defined **data residency zones** to meet regulatory, performance, and availability requirements across geographies. emSign currently supports **two primary data residency zones**: **United States** and **India**. These zones allow customers and relying parties to align with jurisdictional requirements while benefiting from built-in geographic redundancy and low-latency trust services. *** #### United States Data Residency Zone The **United States data residency zone** is supported by data centers located in: * **Salt Lake City, Utah** * **New Jersey** These geographically separated locations provide **intra-region redundancy**, ensuring high availability and resilience for emSign trust services. The use of multiple sites within the U.S. reduces dependency on a single metropolitan area and supports continuity of operations in the event of localized outages or disruptions. *** #### India Data Residency Zone The **India data residency zone** is supported by data centers located in: * **Bangalore** * **Chennai** Both locations operate within Indian jurisdiction, ensuring that trust service data remains resident within the country. The geographic separation between Bangalore and Chennai provides redundancy while delivering performance optimized for customers and relying parties in India and nearby regions. *** #### Geographic Redundancy and Resilience Within each data residency zone, emSign’s architecture is designed for **geographic redundancy**: * Multiple data centers per zone * Isolation between locations to mitigate localized failures * High availability for critical trust services This regional redundancy strengthens service reliability while maintaining strict adherence to data residency boundaries. *** #### Latency Optimization and Regional Choice By offering multiple data residency zones, emSign allows customers and relying parties to choose the region that best meets their: * Regulatory and compliance obligations * Latency and performance requirements * Operational geography Locating trust services closer to users and systems helps reduce response times for certificate issuance, validation, and trust operations. *** #### OCSP Distribution for Low-Latency Validation To ensure fast and reliable certificate status validation globally, **emSign distributes its OCSP (Online Certificate Status Protocol) responders via AWS infrastructure**. This enables: * Low-latency OCSP responses from geographically proximate locations * High availability for certificate revocation checks * Consistent trust validation performance for browsers, operating systems, and applications worldwide The distributed OCSP model complements emSign’s regional data residency architecture by optimizing one of the most latency-sensitive trust operations. *** #### Why emSign Data Residency Matters emSign’s data residency and availability architecture provides: * **Regulatory alignment** with jurisdictional data requirements * **Operational resilience** through multi-location design * **Performance optimization** via regional proximity * **Global trust reliability** through distributed OCSP services --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
