Data sovereignty stopped being a legal compliance checkbox somewhere in the last eighteen months. It’s now a geopolitical risk, an AI governance problem, and a line item increasingly on the CFO’s infrastructure budget.
This series unpacks how that happened and why more organisations are choosing to control their data on-premises instead of a third-party-controlled cloud data storage model.
Part 1: The Residency Illusion Why storing data in a local data centre no longer guarantees sovereignty, and what the U.S. CLOUD Act, EU Tech Sovereignty rules, and AI governance pressures mean for organisations rethinking data control.
Part 2: The €890 Million Fine That Became a Trade War How the EU’s record Digital Markets Act penalty against Google and the Section 301 investigation it triggered turned a search-engine antitrust case into a geopolitical flashpoint over who controls the digital economy.
Part 3: Why 9 in 10 Enterprises Are Coming Back On-Premises The real cost behind cloud repatriation (sovereignty premiums, egress fees, regulatory mandates like DORA and NIS2) and why predictable, owned infrastructure is winning the TCO argument.
Part 4: Beyond Residency: The Five Layers of Data Sovereignty Location is only one layer. UK case studies like UKCloud, 2e2, Nirvanix, Sungard, Global Switch show what happens to ownership, jurisdiction, continuity, and exit control when organisations trust these third-party options.
Together, these four pieces make the same underlying point from different angles: control, not just location, is what sovereignty actually means in 2026. And infrastructure you own outright is the most direct way to get it.
