Outside the app, and before the bad day. When the app can’t load, it can’t explain itself, so the first message has to reach customers where they’re already looking.

Revolut confirmed the disruption through its support account on X and said customers’ money and data were safe. According to The Next Web, its own status page still showed every service as operational at the time. The likely cause was a power event at a Google Cloud data centre near London, and several other UK banks reported problems too. Service came back that evening.

Almost every message a bank relies on lives inside the app: banners, in-app chat, the help centre. During an outage, that is exactly the surface that’s gone.

“Your money is safe” only helps if it reaches people where they’re looking. On 20 October, many of them were looking at an app that wouldn’t load, or at a card that had just been declined in a shop.

Treat the outage as a product flow with its own design, not an incident note written in a hurry.

A cached fallback screen. When the app’s own server calls fail, show a stored “We know there’s a problem. Your money is safe.” screen instead of a generic error. It needs no live backend to render.

A status page that tells the truth. A page that says “operational” while customers can’t pay costs more trust than one that says nothing.

Where should a bank communicate first during an outage?
Where should a bank communicate first during an outage?
Wherever customers can still see it: push notifications, SMS, a status page and social channels, in an order decided in advance. In-app banners and chat fail with the app, so they can’t be the first line.

What is a cached outage screen?
What is a cached outage screen?
A screen stored on the device that the app shows when its own server calls fail. It can say the bank knows about the problem and that money is safe, without needing a live backend.
