A major cloud-service disruption at Amazon Web Services (AWS) knocked out key banking services for millions of UK customers on Monday morning. The incident struck around 8 a.m. UK time and left UK banks including Lloyds Bank, Halifax and Bank of Scotland unable to process online banking or payments.
The root cause lies in DNS and database faults within AWS's US-based infrastructure. While many services have been restored, enquiries are ongoing about how and why the failure occurred — and crucially what affected bank customers should do now.
