Google Cloud outage in London hits banks, financial firms

The significance here is less the outage itself than the concentration risk it exposes: multiple banks and public services failing together because they share one hyperscaler region. That dependency is now a resilience question regulators and operational-risk teams track, not just an IT inconvenience. The political dimension — Downing Street engaging directly with Google — signals cloud reliability is being treated as market infrastructure. The open question is whether such incidents accelerate scrutiny of single-region reliance and third-party concentration across financial firms.
