5.1Assumptions
Scenario SCN-XT08-DEP-01: what is assumed, and what is held constant.
- Baseline
- the 2026 reference state in this edition
- Drivers
- a fault in a shared provider control plane lasts many hours while public services depend on it and sovereignty rules limit failover
- Analogues
- the 2025 events at AWS, Google Cloud and Cloudflare202122
- Interventions
- none modelled: the specification describes the unmitigated case
- Run state
- narrative specification; quantified run scheduled for 2027
5.2The cascade, step by step
- 1
INF → DAT
a control-plane fault interrupts dependent services in one region
2025
- 2
DAT → FIN
payment and business services stall until recovery
2025
- 3
DAT → HLT
hosted records and booking services become unavailable
2025
- 4
GOV → INF
sovereignty rules limit moves between providers or regions
2026
- 5
ENE → INF
recovery load meets local grid limits at the host region
2024
- 6
FIN → INF
customers re-weigh dependence as switching charges end
2025
5.3The scenario as a table of steps
How the shock in scenario SCN-XT08-DEP-01 would travel through Cloud, Edge and Distributed Computing’s coupled systems, step by step, under the assumptions the edition states.
| Step | What happens | Source |
|---|---|---|
| 01 Infrastructure to dat | A control-plane fault interrupts dependent services in one region. Analogue or source: 2025. | Edition XT-08, scenario SCN-XT08-DEP-01, step 1 |
| 02 DAT to finance | Payment and business services stall until recovery. Analogue or source: 2025. | Edition XT-08, scenario SCN-XT08-DEP-01, step 2 |
| 03 DAT to health | Hosted records and booking services become unavailable. Analogue or source: 2025. | Edition XT-08, scenario SCN-XT08-DEP-01, step 3 |
| 04 Governance to infrastructure | Sovereignty rules limit moves between providers or regions. Analogue or source: 2026. | Edition XT-08, scenario SCN-XT08-DEP-01, step 4 |
| 05 Energy to infrastructure | Recovery load meets local grid limits at the host region. Analogue or source: 2024. | Edition XT-08, scenario SCN-XT08-DEP-01, step 5 |
| 06 Finance to infrastructure | Customers re-weigh dependence as switching charges end. Analogue or source: 2025. | Edition XT-08, scenario SCN-XT08-DEP-01, step 6 |
