# Io Faults Caution

{% hint style="warning" %}

* Due to the large blast radius of this fault, we recommend you do not execute it in the production environment.
* Through the fault execution, the application pod can potentially fail to perform successful IO writes if the `write` system call is being targeted. This can cause any data produced in this duration to be lost.
* Any data produced before the execution of the fault is not harmed as a result of its execution.
