Modal Oracle Health (formerly Cerner) cluster: 1449 of 2908 production endpoints (50%) deploy this exact CapabilityStatement shape, concentrated in CA (67), NJ (53), FL (43). This cluster advertises 48 US Core 6.1 profiles in its CapabilityStatement.
A CapabilityStatement shape cluster groups production FHIR endpoints by the exact CapabilityStatement they serve at runtime. Oracle Health (formerly Cerner) publishes one reference CapabilityStatement, but production hospitals deploy several distinct shapes of it — each cluster is one of those shapes.

Oracle Health publishes a two-tier public sandbox (open + secure) — Phase B measurement can run partially without any registration Among the major EHRs measured so far, this two-tier open/secure split is unique to Oracle Health. Epic gates every FHIR resource behind OAuth. The open tier is invaluable for offline measurement (Phase B can partly run without app registration), but it is dangerous to depend on operationally — production Oracle Health customers do not expose this tier, so sandbox-shaped code that relies on no-auth reads will fail in production.

This outlier cluster has too few production endpoints for us to host a dedicated mock under /v/cluster/cerner-patient-cluster-A/ today. The modal Oracle Health (formerly Cerner) cluster is the wire shape that most production deployments use — that's the right starting point for integration testing.
Compatible with Oracle Health's (formerly Cerner Millennium) published FHIR R4 CapabilityStatement across both host fronts: fhir-ehr.cerner.com (provider/EHR-launch tier) and fhir-myrecord.cerner.com (patient standalone-launch tier).
