# Rollback and recovery

Whether you can put the previous version back, and how long that takes.

## Why a check from outside cannot see it

Recovery is a property of your deployment history and your data, not of a page. From the street, an app that can be restored in two minutes looks exactly like one that cannot be restored at all.

## How to check it yourself

1. Deploy a change so small it does not matter, such as a word in the footer.
2. Roll it back using whatever your host gives you, and start a timer when you click.
3. Write down the time, then ask the harder question: what would you do if the change had touched data.

## What a Launch Review does instead

A reviewer deploys a trivial change, rolls it back, times it, and writes down what the data would have needed.
