Microsoft's India Hub Outpaces Its EU Sovereignty Push

Microsoft's Hyderabad Azure region launched complete on 6 August 2026: zero-water cooling, four live customers, $20.5bn committed. Its EU sovereignty pledges took three years and still fall short, say critics.

Microsoft's India Hub Outpaces Its EU Sovereignty Push

Key takeaways

Microsoft's fourth Indian Azure region, India South Central in Hyderabad, went generally available on 6 August 2026 with three availability zones, air-cooled chillers Microsoft says are built for zero water consumption in cooling, and four enterprise anchor customers already live: Adani Group, HDFC Bank, Bajaj Finserv and PB Pay.
The region caps a cumulative $20.5 billion Microsoft commitment to India, built from a $3 billion pledge in January 2025 and a further $17.5 billion in December 2025, alongside contracts for more than 1,000 megawatts of new Indian solar, wind and hybrid power, of which over 630 megawatts is already operational.
Microsoft's nearest EU equivalent, the EU Data Boundary, was first announced in December 2022 and needed three separate phases before reaching its 'completion' milestone in February 2025, and even then it covers where support data and processing happen, not full legal independence from US jurisdiction.
Critics of Microsoft's own November 2025 EU sovereignty update, including Civo chief executive Mark Boost and Nextcloud founder Frank Karlitschek, argue that housing data inside an EU data centre does not remove Microsoft from reach of the US CLOUD Act, and country-by-country Copilot processing still will not reach Germany or Sweden until 2026.
For EU and UK enterprise buyers and policymakers, Hyderabad is now a usable yardstick: Microsoft bundled new physical capacity, an environmental commitment and paying blue-chip customers into one live region in a single announcement, and the fair question is why its EU sovereignty roadmap has needed three-plus years of legal engineering to reach a result critics still call incomplete.

A complete regional hub arrives in one announcement

Microsoft's fourth Azure region in India, India South Central, went generally available on 6 August 2026 in Hyderabad, Telangana, built with three availability zones. It joins existing regions in Pune, Chennai and Mumbai, plus two partnership datacenters run with Reliance Jio, making Hyderabad Microsoft's largest single India hub to date.

Four enterprise customers are already live rather than promised: Adani Group, HDFC Bank, Bajaj Finserv and PB Pay. Microsoft describes the site's cooling as enhanced mechanical cooling with air-cooled chillers, part of what it calls next-generation datacenters that consume zero water for cooling.

20.5 billion dollars and paying customers on day one

The region sits inside a cumulative $20.5 billion commitment to India's cloud and AI infrastructure, built from a $3 billion pledge in January 2025 and a further $17.5 billion announced in December 2025. Microsoft has paired the capital with a skilling pledge: 20 million Indians trained in AI by 2030, with 5.6 million reached since January 2025 and more than 125,000 already moved into jobs or entrepreneurship.

Having Adani Group, HDFC Bank, Bajaj Finserv and PB Pay signed and running at general availability, rather than named as future prospects, is the detail that separates this from a speculative build: it gives Microsoft day-one utilization and gives Indian regulators and customers a working reference for data residency claims before the marketing settles.

What Microsoft actually built for the EU is a legal boundary, not a hub

Microsoft's closest EU equivalent, the EU Data Boundary, was first announced in December 2022. Phase 1 launched in January 2023, Phase 2 followed in January 2024 covering pseudonymized personal data, and Phase 3, covering professional-services data such as support logs and case notes, only reached completion on 26 February 2025. The finished boundary covers Microsoft 365, Dynamics 365, Power Platform and most Azure services.

Microsoft's own announcement of that milestone carries a carve-out: in limited security instances that require a coordinated global response, essential data may still be transferred outside the EU. Completion, in other words, delivered GDPR-adjacent residency for support data, not full data localization and not immunity from US jurisdiction.

Microsoft's own critics call it sovereignty washing

A follow-up announcement in November 2025 promised in-country Microsoft 365 Copilot processing across 15 countries, but only four, the UK, Australia, India and Japan, had it by the end of 2025; Germany, Sweden, the UAE and South Africa are due to follow only in 2026. The same update scaled Azure Local from 16 to a promised hundreds of physical servers and brought Microsoft 365 Local to general availability in connected mode only, with a fully disconnected option pushed to early 2026.

Civo chief executive Mark Boost said putting a data centre in Paris or London means little if the company behind it is still governed by US law. Nextcloud founder Frank Karlitschek called the package sovereignty washing, arguing only open-source software removes the underlying vendor dependency. OpenInfra Foundation's Thierry Carrez put it more cautiously: whether the mix of measures proves sufficient is, in his words, unsure and untested.

The benchmark EU and UK buyers should hold Microsoft to

The two projects are not engineering twins. Hyderabad is a greenfield physical region; the EU sovereignty push retrofits legal and operational controls onto more than a dozen regions that were already mature. That difference matters, but it is not the fair test.

The fair test is completeness and pace when a market matters enough to Microsoft: India got a hard date, an environmental commitment, real capacity and paying anchor customers inside a single announcement. EU and UK buyers weighing sovereign-cloud claims for procurement or compliance, and the policymakers who take Microsoft's commitments at face value, now have grounds to ask why Europe still gets a rolling list of future phases instead of a comparable package delivered at once.

Frequently asked questions

What does Microsoft's zero-water claim for Hyderabad actually cover?

It covers the cooling system only. Microsoft describes air-cooled chillers built for next-generation datacenters that consume zero water for cooling, a narrower claim than covering the site's total water use for construction, staffing or sanitation.

Does the completed EU Data Boundary protect European data from the US CLOUD Act?

No. Microsoft's own announcement reserves the right to transfer essential data in limited security instances that require a coordinated global response, and critics including Civo's chief executive argue that residency without jurisdictional independence does not amount to sovereignty.

When does Microsoft's in-country Copilot processing reach Germany and Sweden?

In 2026, according to Microsoft's own November 2025 announcement, more than three years after the EU Data Boundary was first announced in December 2022 and roughly a year after India's South Central region went live with its full package already in place.

Hyderabad shipped as a complete package: capacity, an environmental commitment and paying customers, all inside one 6 August announcement. EU and UK buyers and regulators now have a dated benchmark to hold Microsoft's slower, thinner European sovereignty promises against.
