Google Cloud Outage Disrupts Revolut Banking Services

Multiple Google Cloud services experienced disruptions in the company’s London region on Tuesday, October 20, affecting digital services and coinciding with an outage at financial technology company Revolut. The disruption raised concerns for customers relying on cloud infrastructure for everyday banking activities, including card payments and cash withdrawals.

Revolut reported that most of its services were unavailable or partially unavailable, according to its status page. A person familiar with the matter told Reuters that the bank’s service disruption was related to the Google Cloud outage.

The incident highlighted the dependence of digital financial services on cloud computing infrastructure. When a cloud provider experiences technical problems, businesses that rely on its services can face interruptions that affect customers even if their own applications and systems have not independently failed.

Google said its engineering team was investigating the issue affecting its London-based europe-west2 data centre. Revolut, meanwhile, reassured customers that their money and data remained safe despite the disruption.

Google Cloud Investigates Disruption in Its London Region

Google Cloud reported problems affecting multiple services in its London region on Tuesday, according to the company’s service status page. The affected infrastructure was identified as the europe-west2 data centre region, which supports cloud services used by businesses and developers.

Cloud computing providers supply remote infrastructure and software capabilities that organisations use to operate applications, store information and process workloads. Instead of maintaining every part of their own technology infrastructure, businesses can rely on cloud platforms to provide computing capacity and related services.

However, this arrangement also means that disruptions affecting a cloud provider can have consequences for customers that depend on the affected services. If a business relies on a particular cloud region for essential workloads, a technical issue in that region may affect its ability to deliver services to users.

Google said its engineering team was investigating the disruption. Alphabet, Google’s parent company, did not immediately respond to a Reuters request for further details.

The available information did not establish the precise technical cause of the outage, how many customers were affected or when all impacted services would return to normal. Those details would be necessary to determine the full scale and duration of the incident.

Revolut Reports Problems With Card Payments and ATM Withdrawals

Revolut was among the financial services providers reporting disruption during the incident. Its status page showed that most of its services were unavailable or partially unavailable, including card payments and ATM withdrawals.

The problems affected functions that customers may depend on for routine transactions. Card payments are used for purchases in shops and online, while ATM withdrawals allow customers to access physical cash. Interruptions to either service can create immediate inconvenience, particularly for people who need to complete transactions while travelling or making everyday purchases.

A person familiar with the matter told Reuters that Revolut’s outage was related to the Google Cloud disruption. This indicates a connection between the cloud incident and the banking service interruption, although the available report did not detail the precise technical pathway through which the disruption affected Revolut.

Revolut addressed the incident in a post on X, stating: “We are currently experiencing a service disruption affecting multiple services. We can confirm that all our customers’ money and data are safe.”

The reassurance addressed two concerns that commonly arise during financial service outages: whether customers can access their money and whether their personal or financial information remains secure. An interruption to service does not automatically mean that funds have been lost or data has been compromised.

Nevertheless, customers may still experience difficulties completing payments, withdrawing cash or accessing other features until the affected services recover. The impact depends on which systems are disrupted and whether alternative processing arrangements are available.

How a Cloud Outage Can Affect Digital Banking

Modern banking applications rely on interconnected technology systems to provide services. A customer’s transaction may involve the banking application, authentication systems, payment processing infrastructure and other services that communicate with one another.

Some of these components may be operated directly by a financial institution, while others may depend on external technology providers. Cloud platforms can supply computing, storage, networking and other capabilities that support applications and business operations.

When an essential cloud service becomes unavailable, dependent applications may struggle to complete requests or communicate with the systems needed to process them. Customers may encounter error messages, delayed transactions, login difficulties or temporary unavailability of particular features.

The effects are not necessarily identical across all services. An application may continue to open while a payment function fails, or customers may be able to access account information but encounter problems with transactions. The outcome depends on how the business’s systems are designed and which components are affected.

Cloud outages can also create challenges for technical teams attempting to identify the source of a problem. When a service depends on several providers and interconnected systems, engineers may need to establish whether the failure originates in their own infrastructure, a third-party platform or a connection between the two.

In the Revolut incident, the reported link to Google Cloud illustrates how a disruption affecting one technology provider can extend to a separate business and its customers. It also underscores why financial companies need clear incident-response procedures and contingency plans for disruptions involving external infrastructure.

Why Cloud Reliability Matters for Financial Services

Cloud computing has become an important part of the technology landscape for businesses operating digital services. It can help organisations scale computing resources, deploy applications and manage infrastructure without building every system independently.

For financial institutions and digital banks, however, availability is especially important. Customers expect to be able to check balances, transfer money, make purchases and withdraw cash when needed. Even a temporary outage can disrupt these activities and affect confidence in a service.

Reliability therefore depends on more than the performance of an individual application. It can also depend on the availability of infrastructure providers, network connections, authentication services and other supporting systems.

Businesses can reduce some risks by designing systems to tolerate failures. Depending on their needs and architecture, possible measures include using backup systems, distributing workloads across separate infrastructure environments, maintaining alternative processing arrangements and testing recovery procedures.

However, resilience is not automatic. Running systems across multiple locations or providers can increase complexity and cost, and it does not guarantee that every component will remain available during an incident. Companies must identify which services are most critical and decide how much redundancy is appropriate.

The disruption also highlights the importance of communication. Clear status updates can help customers understand which services are affected, whether their transactions are likely to be delayed and when further information will be available.

ING Germany Also Reports Online Banking Problems

Separately, ING Germany reported problems with logging into online banking and its banking application because of a technical issue, according to the Reuters report.

The report did not establish that ING’s problems were connected to the Google Cloud disruption affecting Revolut. The two incidents should therefore be treated separately unless further information confirms a common cause.

Online banking login problems can prevent customers from accessing account information or carrying out digital transactions. However, the precise impact depends on the nature of the technical issue and the services affected.

The simultaneous reports of disruptions at different financial service providers drew attention to the operational risks facing digital banking. Still, the available information did not establish that the incidents formed part of a broader banking-system failure.

Determining whether multiple outages are connected requires technical evidence, including information about affected infrastructure, service dependencies and the timing of failures. Similar customer-facing symptoms do not necessarily indicate a shared underlying cause.

What Customers Should Do During a Banking Service Outage

When a digital bank reports a service disruption, customers can take several practical steps to reduce uncertainty and avoid unnecessary risks.

• Check official status updates: Consult the bank’s official service status page or verified communication channels for information about affected services and recovery progress.
• Avoid repeatedly attempting failed transactions: If a payment or withdrawal fails, check the transaction status before trying again, where possible, to reduce the risk of duplicate attempts.
• Keep alternative payment options available: Where practical, having another payment method or access to cash can help during temporary card or banking disruptions.
• Monitor account activity: Once services recover, review recent transactions and contact the bank through official channels if an unexpected charge or unresolved transaction appears.
• Be cautious of scam messages: Outages can create opportunities for fraudsters to impersonate banks or cloud providers. Do not share passwords, one-time passcodes or other security credentials in response to unsolicited messages.

Customers should also distinguish between a service outage and a security incident. An inability to access an application does not, by itself, indicate that an account has been compromised. Revolut explicitly stated that customer money and data were safe, although customers should continue to follow official updates from the company.

What Remains Unknown About the Google Cloud Outage

At the time of the Reuters report, Google was investigating the disruption affecting its London region. The available information did not specify the underlying technical cause, the full number of affected Google Cloud customers or the expected time needed to restore all services.

Further details would be needed to assess whether the incident involved a specific cloud service, a wider regional infrastructure problem or another technical issue. The distinction matters because the scope and duration of an outage can influence how businesses respond and what safeguards they may need to strengthen.

It was also unclear from the supplied report which individual Revolut services had recovered, whether customers in particular locations were more severely affected or how long the banking disruption would last.

For businesses that rely on cloud infrastructure, the incident may prompt renewed scrutiny of service dependencies and recovery plans. However, conclusions about the adequacy of any company’s infrastructure would require more information than the initial outage report provides.

Conclusion: Google Cloud Disruption Highlights Digital Banking Risks

The Google Cloud outage in London on October 20 disrupted multiple services in the europe-west2 region and was linked to service problems at Revolut, according to a person familiar with the matter cited by Reuters. Revolut reported that card payments, ATM withdrawals and other functions were unavailable or partially unavailable.

Google said its engineering team was investigating the issue, while Revolut reassured customers that their money and data were safe. Separately, ING Germany reported login problems affecting its online banking service and mobile application, although no connection between the ING incident and the Google Cloud disruption was established in the report.

The incident demonstrates how digital banking services can be affected by problems involving external technology infrastructure. Cloud platforms provide important capabilities for modern businesses, but outages can create operational challenges when essential services depend on affected systems.

The immediate priorities are to restore affected services, communicate clearly with customers and establish the cause of the disruption. For the wider financial technology industry, the event reinforces the importance of resilient infrastructure, tested recovery arrangements and transparent incident management as more everyday financial activity moves online.
