failure
Parameters
value
The percentage of accounts, per Region, for which this stack operation can fail before CloudFormation stops the operation in that Region. If the operation is stopped in a Region, CloudFormation doesn't attempt the operation in any subsequent Regions. When calculating the number of accounts based on the specified percentage, CloudFormation rounds down to the next whole number. Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage , but not both.
