Revolut outage caused by Google Cloud failure reopens tech sovereignty debate

Revolut goes down after a Google Cloud failure and Europe takes another hard look at its tech dependence

A bank with no branches, an app that won't open and thousands of people stuck at the checkout unable to pay. The Revolut outage, one of the world's largest neobanks, left customers across Europe —Spain included— unable to access their accounts, and the cause points to a failure in Google Cloud, specifically in the europe-west2 region, located in London. Google confirmed the incident and recommended migrating the workload to another location as a temporary fix. The company says no customer data was compromised.

The scare has two layers. The first is the obvious one: a failure at a third-party provider leaves thousands of people unable to withdraw money or pay by card. The second is the one that matters to those looking beyond the ticket: the concentration of critical services in a single infrastructure, in a single region, under the control of a tech company that answers to no one in Brussels.

What exactly peine with Revolut and Google Cloud

The sequence is easy to tell and hard to swallow. Google Cloud recorded a failure in its europe-west2 region, based in the British capital. Revolut, which runs on that infrastructure, saw its services degrade: card payments, cash withdrawals and access to the app. The incident was felt in Spain and also in the UK, where it was linked to problems at other companies such as the property platform Rightmove. Outside that orbit, other banks such as ING Germany were also struggling with online banking access, though no link was confirmed.

Google's response was the usual one: the affected customer can try migrating the workload to another available location. In other words: if your house floods, move the furniture elsewhere. How agile.

The money doesn't disappear, the access does

It's worth separating panic from accounting. Balances remain on the bank's records and, in Revolut's case, are covered up to €100,000 by Lithuania's deposit guarantee fund, where it holds its banking licence. What goes down is the door: the app, the card, the ATM. It's a serious inconvenience, not a loss of wealth.

Even so, the scene repeats itself in any supermarket queue: someone in front of you holding up their phone, the cashier staring at the card terminal, and you clutching a 40-euro note feeling like an endangered species. Cash, that poor relation of digital money, saved the purchase.

Why does a service go down if there are thousands of data centres?

Here's the technical knot almost nobody explains. It's not a lack of capacity: Europe has data centres to spare. What fails is the design. Many organisations concentrate critical services with a single provider and, worse, in a single region. When that point breaks, the impact spreads because switching infrastructure doesn't happen overnight.

The prescription repeated in every analysis is threefold: multicloud, real-time monitoring and recovery plans. Multicloud doesn't fix everything, but it spreads the risk. And above all, as the industry points out, Europe has enough technology not to depend on a single foreign giant. The Cloudflare outage in its day already left a trail of companies down.

The fine print: nobody picks up the phone

Beyond the technical failure, the outage exposed the other hole: customer service. Anyone trying to resolve a blocked transfer ran into an AI that doesn't understand, a chat that passes you to another department that never arrives, and the feeling of talking to a wall. In more than one case, the solution came through public shaming on social media, not through the official channel.

There's the underlying problem. A branchless bank saves fixed costs and turns them into a pretty app. When the app fails, there's nothing behind it.

Tech sovereignty: from rhetoric to the bill

The episode reopens a debate Europe has been postponing for years. Digitalisation advances, regulation multiplies, but the infrastructure underpinning that regulation belongs to others. A failure in a London region can leave half of Europe unable to pay. That's not a provider problem: it's a dependency problem.

Is demanding multicloud enough? Or is something more structural needed — a European infrastructure capable of sustaining critical services without asking a third party for permission? The answer isn't in Google's statement or Revolut's. It's in the next outage, which will come. The only question is whether by then someone will have moved the furniture in time.
