Must data be hosted in Brazil?

Bill PL 278/2026, passed by the Senate on 2 September 2026 and sent for sanction, sets a tax regime for data centres with commitments on investment, renewable energy and water efficiency. The Nuvem Brasileira programme, opened to market listening through public consultation notice no. 1/2026, states as its objective an infrastructure located inside national borders and subject to Brazilian law.

Which systems does the index cover?

Version 2026.1 of the census holds %systems% federal systems: the 1,610 domains of the gov.br register published by the Secretaria de Governo Digital, plus the federal institutions that sit outside that zone, among them the higher courts (.jus.br), the two chambers (.leg.br) and the armed forces (.mil.br).

Does a server hosted in São Paulo count as national?

The index reads the jurisdiction of the network announcing the address. A system served from the Brazilian region of a foreign provider is counted under that provider's jurisdiction, which is the same distinction the Nuvem Brasileira draws between an infrastructure located inside the borders and one subject to Brazilian law.

How is this index computed?

Every week, the A, AAAA, MX and NS records of each censused system are resolved from 1.1.1.1, then each address is attributed to the autonomous system announcing it, whose regional registry gives the country of registration. The national share of an axis is the share of systems whose resolved addresses are all announced from a network registered in the country. The method and the anycast frontal list are published and versioned.

The Stileex Digital Sovereignty Index (SDSI) reads three axes of every censused system each week: where its site answers from, where its mail lands, and who holds its name.

On 21/09/2026, across the 1,624 systems of the census, 74.2 % serve their site from networks registered in Brazil, 38.8 % receive their mail there, and 67.1 % have their authoritative DNS there.

By sector

Version 2026.1 of the census is the federal administration, read on the same three axes. In brackets, the number of systems the axis places a hosting for.

Sector	Site	Mail	Authoritative DNS	Systems
Federal administration	74.2 % (821)	38.8 % (521)	67.1 % (1345)	1624

The share is computed over the systems whose axis places a hosting; the last column gives the sector's censused headcount.

Countries the sites are served from

The country of registration of the network announcing each address serving the site. A system answering from two countries counts in both.

The frame under examination

Bill PL 278/2026 sets a tax regime for data centres, with commitments on investment, renewable energy and water efficiency. It was passed by the Senate on 2 September 2026 and sent for sanction.

In parallel, the Nuvem Brasileira, carried by ABDI with the Ministry of Management and Innovation in Public Services, Serpro and BNDES, opened its market listening phase through public consultation notice no. 1/2026. Its stated objective is an infrastructure located inside national borders and subject to Brazilian law.

The index reads the infrastructure serving the systems, as observed on the public network, on the date of each reading. What it establishes is the JURISDICTION of the network announcing an address: a system served from the Brazilian region of a foreign provider is counted under that provider's jurisdiction. That is the same distinction the Nuvem Brasileira draws between an infrastructure located inside the borders and one subject to Brazilian law.

Who operates those networks, provider by provider: the public cloud in the federal government

The same census, read for mail and DNS authentication: DMARC, SPF and DNSSEC in the federal government

The same census, read for the Internet protocol: IPv6 in the federal government

How it is measured

Census: 1,624 systems: the 1,610 domains of the gov.br register the Secretaria de Governo Digital publishes on dados.gov.br, in a snapshot dated 20 October 2022 kept with the index, plus the federal institutions that sit outside that zone (.jus.br, .leg.br, .mil.br, .mp.br). A census version is dated; an entity that leaves is retired, never deleted, its past readings remaining part of the series.
Cadence: One reading a week, on Mondays. Hosting moves on a quarterly scale: weekly is what lets a migration be dated to the week.
Reading: A, AAAA, MX and NS records resolved from 1.1.1.1, then each address attributed to the autonomous system announcing it through the Team Cymru DNS service. The country is the one that autonomous system is registered under at its regional registry, cross-checkable against the delegation files LACNIC publishes daily.
Four states: National when every resolved address is announced from a network registered in the country; foreign when none is; intermediary as soon as one address belongs to an anycast frontal of the list published with the method, Azion included; mixed when national and foreign resolutions coexist. No answer is a measured state, counted in the denominator.
Base: The published shares cover the systems whose axis places a hosting, that is 50.6 % of the census on the site axis.
Method version: Every point carries the method version in force on its date, version 3 today. Read the method
