Understand change and outage impact before it surprises the business.
CMDBx uses ServiceNow CMDB topology to simulate blast radius, helping change managers, service owners, and incident teams understand which CIs and services may be affected by a planned or unplanned event.
Assess maintenance and deployment impact before CAB review.
Identify downstream services and applications at risk.
Support incident triage with relationship-backed impact evidence.
Evidence that can survive operational review.
Built from ServiceNow CI relationship data with deterministic, versioned propagation rules.
Shows impact paths, alternate routes, excluded relationships, and single points of failure.
Reports evidence confidence, freshness, and completeness separately from risk.
How does CMDBx calculate blast radius?
CMDBx follows outage-propagating ServiceNow relationships from a selected CI to the CIs and services that depend on it. Deterministic rules decide which relationships carry impact, and the result records every path, every excluded relationship, and whether a depth, size, or time limit ended the analysis early.
Can blast radius analysis support CAB decisions?
Yes. CMDBx can analyze every affected CI on a change request as one graph and return shared impact, redundancy, single points of failure, and a ready-to-post work note. The PDF and CSV exports come from the saved result, so the evidence CAB reviews does not change after the fact.
