Cloud region labels often hide multiple data journeys. A vendor can store a resource in one region while a connected model or separate feature processes data somewhere else.
Distinguish storage and inference
A model endpoint may have a deployment geography distinct from the location of its vector database, telemetry, batch evaluation results and human support. The word “resident” must specify which datasets, which operations and which actors are covered. Cross-border legal access and contractual processors need separate analysis.
A documented service counterexample
Microsoft’s September 2026 Azure SRE Agent privacy documentation says the agent stores and processes certain data in the selected region but notes that model inference may occur outside that region, depending on provider selection. By contrast, separate Azure AI Content Safety documentation describes regional handling for that service. Neither statement should be generalized to every Azure AI capability.
Build the service-feature register
Create one row for each product feature: base chat, file upload, search indexing, embeddings, realtime audio, agents, content safety, fine-tuning, evaluation and logs. Include selected region, allowed inference locations, monitoring, backups, support geography, account eligibility, source URL and verification date. An unknown cell is safer than treating the regional name as full proof.
Verification sequence
Read official technical data-handling pages, order forms and deployment documentation; then confirm account-specific routing settings. Test non-sensitive traffic against logging and policy settings where technically possible, without assuming packet inspection reveals all provider-side operations. Obtain contractual commitments when residency is mandatory rather than treating a settings screenshot as an audit certificate.
Reason for review status
This is a method and a documented Azure counterexample, not a verified all-provider matrix. Other vendors’ current regional endpoints, contracting options and specialized-feature behavior were not exhaustively assessed on the cutoff date. Those cells remain null and require AI10/provider-level source verification.
