Alert overload
Engineers had to work through large volumes of warnings and telemetry across multiple clusters before isolating the real source of failure.
Customer success story · Deutsche Bahn
Deutsche Bahn: faster incident diagnosis inside strict data-handling boundaries
Hyground operated inside Deutsche Bahn's environment to accelerate root-cause analysis in passenger information systems without sending operational data outside the VPC. 8-week proof of concept, DB Reisendeninformation, distributed Kubernetes environment.
The challenge
Distributed Operational Friction
Deutsche Bahn's passenger information systems operate in a distributed cloud environment with multiple Kubernetes clusters, large telemetry volumes, and strict requirements for reliability and data handling.
"In stressful on-call situations, Hyground helped us access the exact system knowledge we needed much faster." PoC Team Member, DB RIS
The solution
Perimeter-Bounded Autonomy
Hyground was deployed in a dedicated sandbox cluster inside Deutsche Bahn's environment and connected to the existing toolchain with read-only investigation paths.
Customer-controlled deployment
Deployment via Helm chart and integrated with systems such as OpenSearch, Prometheus, and Kubernetes without changing the production operating model.
Context-aware investigation
Hyground used telemetry and internal context to accelerate root-cause analysis and surface the relevant system knowledge for the on-call engineer.
Human-governed workflow
Engineers received evidence-based findings and retained control over any production decision or action.
Results
Sovereign SRE Enablement
"Based on the positive results, the rollout expanded toward additional business-critical applications and clusters." PoC Lead, DB RIS
Faster investigation
The proof of concept materially reduced investigation time, including workflows in which root-cause assessment was produced in under five minutes.
Under 5 min
Root-cause assessment
Up to 85% lower MTTR
Across the tested workflows, mean time to resolution dropped by as much as 85%, with deployment confined inside Deutsche Bahn's VPC.
Up to 85%
Lower MTTR
Broader team enablement
System knowledge became more accessible across the SRE team, reducing dependence on a small number of subject-matter experts.
Control preserved
Operational data remained inside Deutsche Bahn's VPC, supporting the organisation's data-handling requirements.
