Revolut outage stopped crypto transfers

Revolut customers across Europe woke up to an app that would not open and cards that would not pay. Sending and receiving crypto stopped with everything else. The company's own status page listed 31 services as partially unavailable, among them card payments, transfers, ATM withdrawals and signing in, and Downdetector logged more than 1,500 reports from the UK, France, Romania and Spain.

Where the failure actually was

The cause sits one floor below Revolut. Google Cloud opened an incident for its europe-west2 region in London at 06:08 UTC, which is 08:08 in Kyiv and Warsaw, the hour users started noticing. The entry lists 38 affected products, including Compute Engine, Kubernetes Engine, Cloud SQL, Cloud Storage, Spanner, Firestore, Pub/Sub and Cloud Load Balancing. Google rates the severity medium and the incident was still open at 09:24 UTC.

Why cards failed in shops

That list explains why cards failed in shops, which rarely happens during an app outage. A payment card does not talk to the app. It talks to an authorisation service, and when load balancing and the databases behind it sit in one region that has stopped answering, the terminal gets a decline rather than a spinning wheel.

Revolut said customer money and data are safe, apologised and put engineers on it. Nothing in the public record suggests anything was lost, and an outage is not a breach. What it is instead is a measurement: how much of a fintech lives in one cloud region.

“All our customers' money and data are safe.”

What it says about custody

The crypto part is worth stating plainly. Bitcoin kept producing blocks through the whole window, ten of them in the first four hours of the incident, and the chains themselves never noticed. What stopped was one company's access to them. A balance inside Revolut is a record in Revolut's systems, and when those systems are down the coins exist but you do not reach them.

This is the same trade two other stories made this month. German savings banks began selling crypto with DekaBank holding the keys in an omnibus wallet, and Visa and Mesh are building a way to pay from a wallet balance through a credential provisioned in the background. Both make crypto easier to use by putting a company between the holder and the asset. Tuesday morning showed what that costs on the day the company's cloud region goes down.

Two things settle this. Whether Google publishes a cause for a London region failure that took 38 products with it, and whether Revolut says how many of its services depend on a single region. Neither answer changes today's balance, and both decide how often this repeats.

Informational material, not investment advice. The incident was still open when this was written, and the final cause may be described differently once both companies publish their reports.
