To check why a resource update failed, use the DescribeStackResources action, and view the resource status reason.   Specify this property to skip rolling back resources that AWS CloudFormation can't successfully roll back. We recommend that you  troubleshoot resources before skipping them. AWS CloudFormation sets the status of the specified resources to UPDATE_COMPLETE and continues to roll back the stack.

Before performing another stack update, you must update the stack or resources to be consistent with each other. If you don't, subsequent stack updates might fail, and the stack will become unrecoverable.   Specify the minimum number of resources required to successfully roll back your stack. For example, a failed resource update might cause dependent resources to fail. In this case, it might not be necessary to skip the dependent resources.  To skip resources that are part of nested stacks, use the following format: NestedStackName.ResourceLogicalID. If you want to specify the logical ID of a stack resource (Type: AWS::CloudFormation::Stack) in the ResourcesToSkip list, then its corresponding embedded stack must be in one of the following states: DELETE_IN_PROGRESS, DELETE_COMPLETE, or DELETE_FAILED.
