A versioned DevOps change can break a customer flow while application code stays untouched.
Application review passes runtime behaviour breaks
The change looks operational. The consequence appears in the product.
Review sees
A valid configuration or route.
Customers experience
A flow that no longer works.
The change starts in release configuration
A versioned route or environment definition changes which service handles a request.
Infrastructure changed application code did not
Change in configuration failure in the product
The regression appears in the product
The symptom can surface in login, checkout or another customer-facing flow far from the infrastructure change.
