Amazon’s recent global cloud outage has highlighted the extent of the UK government’s dependence on Amazon Web Services AWS and the growing risks to continuity of public services. The disruption left thousands of companies in limbo and put a spotlight on the 17 billion pound reliance that the state holds with the US tech giant according to procurement intelligence from Tussell.

AWS has secured 189 UK government contracts since 2016 tallying up to 14 billion pounds invoiced and 11 billion pounds currently in play across 35 public sector authorities These include ministerial departments such as the Home Office DWP HMRC Ministry of Justice Cabinet Office and Defra. As the outage hit on Monday 20 October the HMRC in particular confirmed accessibility issues and asked customers to bear with them as phone lines also faced increased demand.

This single point of failure exposes a structural risk previously highlighted by UK regulators including the Treasury and Financial Conduct Authority FCA The FCA and Prudential Regulation Authority PRA have repeatedly warned about the dangers of concentration risk when critical infrastructure is dominated by only one or two cloud providers Recent moves from the Treasury PRA and FCA aim to bolster oversight of critical third parties but the incident suggests that the pace of regulatory alignment may not match the rate of digital adoption within government.

The House of Commons treasury committee has raised concerns that despite AWS powering resilience strategies for the financial sector the government has yet to designate Amazon as a critical third party — a step that would put the company under direct regulatory oversight for its UK financial services activities Multiple departments rely on AWS’s “multiple layers of protection” for continuity but the real world test offered by this outage has amplified questions about digital resilience and diversification strategies

Beyond technical and regulatory audibility Amazon’s treatment of its workforce has also drawn chronic criticism from unions and politicians Andy Prendergast of the GMB union described workplace conditions as shocking with repeated ambulance callouts and accusations of poverty pay conditions Unions argue such a record should be incompatible with receiving almost 2 billion pounds of public money through vital government contracts

Services were largely restored within hours but the incident has left a clear challenge for ministers and civil servants The UK government’s heavy reliance on one global tech company not only puts essential public infrastructure at risk in the event of further outages but creates a policy contradiction with the risk management principles their own regulators advocate
