Service Not Available page for an unavailable store
Key Takeaway
You customize the Service Not Available page in Experience Builder when a CDN is enabled for the store. For an LWR store, connecting the store to a domain turns on the Salesforce CDN automatically.
The Service Not Available page is an offline page that shoppers and buyers see when a B2B Commerce store is unavailable, for example during an outage, during maintenance, or after the site is deactivated. When a CDN is enabled for the store, you can customize the page in Experience Builder with your own brand and message. Buyers then get a clear, branded message instead of a site that fails to load.
When the page appears
The Service Not Available page is an offline page, so it appears only when the store isn't available. While the store is up and running, the page has no effect on what buyers see.
