   Google says services recovering after cloud outage hits UK banks and websites

   BBC NewsPublished Oct 20, 2026Checked Oct 20, 2026

   “Revolut was among UK banking services seemingly affected by the Google Cloud outage on Tuesday Google Cloud says services are recovering after a "power event" at its UK cloud site caused an outage affecting UK banks, businesses and the courts. The company, one of a few large cloud computing firms whose infrastructure and services underpin many online platforms, reported an "issue with multiple services" at its London data centre complex "europe-west2." Revolut, Lloyds Bank and HSBC confirmed disruption to some services on Tuesday morning, after thousands of reports of problems were raised by users online. While the banks did not directly link the issues to the Google Cloud outage, the company has apologised "to all who are affected by the disruption". A host of popular British platforms and services appeared to have been affected during Tuesday's outage - with customers flagging issues with sites including Royal Mail, DPD and e-bike service Forest. The HM Courts and Tribunals Service also said it was aware of an issue affecting the video platform used for remote hearings. Banks appeared to be among the most badly affected, with customers reporting problems ranging from being unable to access funds abroad to struggling to complete a property purchase. Rachael Ellen, 25, a Revolut customer from Glasgow, told BBC News she was left unable to access her money.”

   Globally Critical Infrastructure: The Unique Risks and Challenges.

   “Risk management entails unique challenges, because countries dependent on that infrastructure may have no legal or regulatory authority to shape risk management practices at facilities in other countries. Consequently, risk management may extend beyond the domains of the typical homeland or internal affairs agencies to include capabilities and responsibilities of ministries of foreign affairs, trade and commerce, and defense. However, those challenges also imply new risk management demands and options, such as new avenues for international cooperation on infrastructure protection and resilience, international funding, and enhanced monitoring. Having a globally critical infrastructure system in its borders changes the risk dynamics for a nation state, creating potential leverage over dependent nations and new avenues to garner international support, but also creates new risks to national sovereignty. Recognizing these common dependencies can better enable the global community to engage stakeholders to develop and implement systemic risk management approaches worldwide.”

   Assessing the Sensitivities of Input-Output Methods for Natural Hazard-Induced Power Outage Macroeconomic Impacts.

   “Our analysis evaluates the sensitivity of three commonly used data parameterization techniques (household interruptions, kWh lost, and satellite luminosity), along with three static models (Leontief and Ghosh, critical input, and inoperability input-output). We find the mean domestic loss estimates for these three blackout events to be $2.42 Bn, $3.24 Bn, and $2.27 Bn, respectively. However, data parameterization techniques can alter estimated losses by up to 52.8% of the mean. Consistent with the wide range of outputs, we find that risk analysis stemming from gross output estimate severity is highly sensitive to model architecture, data parameterization, and analyst assumptions. Results sensitivity is not uniform across models and arises from important a priori analyst decisions, demonstrated by data parameterization techniques yielding up to 55.9% differences from empircal results within a model. To our knowledge, we contribute to the literature the first systematic comparison of multiple IO models and parameterizations across several natural hazard long-duration power outages, providing guidance and insights for analysts.”

   “Cloud computing is defined by the International Organization for Standardization (ISO) as "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on demand". It is commonly referred to as "the cloud".”
