UK Businesses Face £1 Billion Risk from Cloud Outages

• •Over 60% of UK companies depend on cloud services for critical functions.
• •A 24-hour outage in AWS or Azure could result in losses of £650 million to £1 billion.
• •80% of UK firms rely on AWS, Google Cloud, or Microsoft Azure, indicating systemic risk.

A report from the Cyber Monitoring Centre reveals that over 60% of UK companies rely on cloud services for critical operations, with dependence rising to over 80% among FTSE 100 firms. A 24-hour outage in major AWS or Azure regions could lead to direct revenue losses ranging from £650 million to £1 billion. The report highlights AWS's eu-west-1 and us-east-1 regions as critical points for potential outages. While only 11% of companies are classified as 'cloud-dependent,' this figure increases to 64% when weighted by revenue. The report emphasizes the systemic vulnerabilities created by this concentration of cloud services. Past incidents, such as a DNS management flaw in AWS, have shown the potential for widespread disruption. The findings call for coordinated action from businesses and policymakers to address these vulnerabilities.
