Data residency + sovereignty for AI ITSM (May 2026)

Source report: /tmp/data-residency-sovereignty-2026-05-12.md (305 lines, ~37KB).

Atomicwork hosting correction (material wiki update)

The May 12 2026 research pass surfaced that Atomicwork’s public security page references AWS RDS encryption on the data plane, contradicting the wiki’s prior framing of “Azure AI Foundry hosting” as the whole stack.

  • Likely reality: Azure for AI / model inference + AWS RDS for tenant data plane.
  • This partly weakens the “must mirror Atomicwork’s Microsoft co-sell” thesis (channel-partnership-roadmap-2026).
  • Wiki entity updated May 12 2026.

Regulatory landscape (residency delta)

This page is the residency delta on top of ai-itsm-compliance-roadmap-2026 + asia-pacific-ai-itsm-2026 — it does not re-derive the broader regulatory landscape.

India

  • Negative-list model — no countries on the list as of May 2026.
  • US-hosted is legally permitted for Indian DPDP-scope customers.
  • Data-residency is procurement-preferred, NOT legally required.

EU

  • AWS European Sovereign Cloud (Brandenburg) Jan 15, 2026 = first hyperscaler sovereign offering.

Notes

Open follow-ups

  • Atomicwork hosting split needs further triangulation (Azure-only vs Azure+AWS) before competitive-positioning slides reference it.
  • Atlassian Isolated Cloud GA status as of May-Oct 2026 — watch announcements.
  • FedRAMP 20x Phase 3 public adoption Q3-Q4 2026 — re-evaluate FedRAMP timing if any govt-ARR pipeline emerges.
