AWS Reports European Sovereign Cloud Independence Exercise

Summary
AWS says a 2026 exercise switched off the European Sovereign Cloud’s links to its global network and local operational-data system. Traffic rerouted over the public internet while workloads and customer access continued without reported service impact.

- The team switched off the AWS Global Network backbone and a local system for controlled operational-data transfers; traffic normally using the backbone rerouted over the public internet.
- AWS reports that workloads continued running and customers retained data access, with no service availability impact to the European Sovereign Cloud or other AWS Regions.
- AWS says the exercise produced technical and operational evidence for organizations seeking to demonstrate sovereignty and continuity to regulators and boards.
