+In case `FailedNodeStartupTimeout` is undefined default behaviour is preserved (i.e. remediation is not postponed).
+The Pro is that naive users aren't being surprised with a new behavior however, the con is that naive users do benefit from the new behavior.

 ## Alternatives
 
-- Instead of delaying, canceling the remediation for failed machines.

-## Infrastructure Needed [optional]
-
-Use this section if you need things from the project. Examples include a new
-subproject, repos requested, github details, and/or testing infrastructure.
+In case a machine enters the `Failed` state and does not have a NodeRef or a ProviderID do not perform remediation on that machine.
 
-Listing these here allows the community to get the process for these resources
-started right away.
+This alternative is simpler since it does not require `FailedNodeStartupTimeout` however it does not allow an option to retain the system previous behaviour and relies completely on manual fix of the failed machines.
