For public, nonpersonalized content, a short stale window can keep a storefront usable during an origin failure. Never use stale responses for carts, accounts, or private data.

## Set the failure rule before launch

Write down the timeout, fallback, and owner. Test the normal path and one real failure. If the customer cannot keep shopping when a dependency breaks, the fallback is not finished.

## Bottom line

For public, nonpersonalized content, a short stale window can keep a storefront usable during an origin failure. Never use stale responses for carts, accounts, or private data.

## Frequently asked questions

### When is serving stale content the right call during an outage?

For public, nonpersonalized pages such as product and content pages, serving a recent cached version for a short window keeps the storefront usable while the origin recovers. The stale window should be defined in advance, with a timeout and an owner, rather than improvised during the incident.

### Which pages should never be served stale?

Carts, account pages, checkout, and anything containing private or personalized data. A stale version of a public page is an inconvenience. A stale version of a private page can show one customer another customer's information, which is a privacy incident.

### How should a store test its stale fallback before launch?

Test the normal path and at least one real failure, with the fallback rule written down first: the timeout, what gets served, and who owns the decision. If customers cannot keep shopping when a dependency breaks, the fallback is not finished.
