On October 24, 2026, AWS will conduct an exercise to demonstrate the independent operation of its European Sovereign Cloud. For several hours, the cloud will operate without a connection to the AWS Global Network backbone, which is AWS's private network for operational data transfer between AWS locations. During this period, authorized AWS operational data will securely reroute over the public internet.
The exercise is not expected to affect service availability within the AWS European Sovereign Cloud, other AWS Regions, or private connectivity via AWS Direct Connect. Customers may experience brief connectivity disruptions at the beginning and end of the exercise as traffic switches network routes, after which normal connectivity will resume.
The exercise will be executed by an operational team composed entirely of EU residents located within the EU. This team will use only the hardware and software resources of the AWS European Sovereign Cloud. The Managing Directors of the AWS European Sovereign Cloud initiated this exercise to showcase its operational independence.
The AWS European Sovereign Cloud is a new, independent cloud located in Brandenburg, Germany. Its data centers are physically and logically separate from other AWS Regions and include a local, in-EU copy of the source code. All customer content and metadata remain within the EU, and the cloud is operated exclusively by EU residents, with no critical dependencies on non-EU infrastructure.
This exercise aims to produce verifiable technical and operational evidence of the AWS European Sovereign Cloud's ability to operate independently within the EU. It is designed to align with regulatory standards requiring operational independence for sovereign cloud environments.

AWS will conduct an exercise on October 24, 2026, to demonstrate that its European Sovereign Cloud can operate independently of non-EU infrastructure. During this period, the cloud will function without a connection to the AWS Global Network backbone, with traffic rerouted over the public internet, to verify its operational independence for European customers.
