Madagascar data residency: where the systems answer from

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 05/09/2026, across the 118 systems of the census, 40.7 % serve their site from networks registered in Madagascar, 41.0 % receive their mail there, and 6.8 % have their authoritative DNS there.

Site

40.7 %

7.4 % behind an anycast frontal, over the 91.5 % of the census this axis places a hosting for.

Mail

41.0 %

0.0 % behind an anycast frontal, over the 70.3 % of the census this axis places a hosting for.

Authoritative DNS

6.8 %

9.4 % behind an anycast frontal, over the 99.2 % of the census this axis places a hosting for.

By sector

The three sectors article 11 of the draft law names, each read on the same three axes. In brackets, the number of systems the axis places a hosting for.

Sector Site Mail Authoritative DNS Systems
Government and public administration 47.8 % (90) 43.3 % (67) 5.1 % (99) 100
Financial sector 7.1 % (14) 25.0 % (12) 14.3 % (14) 14
Health sector 0.0 % (4) 50.0 % (4) 25.0 % (4) 4

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.

National host networks

The autonomous systems registered in Madagascar that serve the censused sites, and how many each hosts.

What the territory can host

The other side of the obligation, read on 5 September 2026 from the AFRINIC delegation files and from datacentermap.com.

Autonomous systems
11 autonomous systems are registered to Madagascar at AFRINIC.
IPv4 addresses
579,840 IPv4 addresses are allocated to the country.
Data centres
3 facilities on record, with one operator, including TNR02 in Antananarivo, Tier III.

Round trip from Antananarivo

A TCP handshake timed from our Ilafy office, on Malagasy links, on 05/09/2026: 83 systems answered, 35 stayed silent. The resolution reads a registration; this timing is a physical fact about distance, and it sheds light on the systems an anycast frontal answers for.

State Systems Median round trip
National 34 323.9 ms
Foreign 41 298.6 ms
Intermediary 8 173.1 ms

Measured from stpc11, best of the attempts kept: what is measured is the distance travelled, and any disturbance on the way can only add to it. The vantage point travels with the figure, the same host timed elsewhere not saying the same thing.

The frame under examination

Draft law no. 040/2026 on electronic communications and digital infrastructure provides that administrative, critical or essential data be hosted on national territory, with a data centre operator declared and certified under a list set by ministerial order (article 10).

Its article 11 extends the obligation to every organisation and company established in Madagascar that collects, processes or stores data generated on the territory, and names three sectors: the financial sector, the health sector, and government and public administration. A cumulative exemption covers organisations with fewer than 50 employees and under one billion ariary of annual turnover. Copying outside the territory remains allowed as long as the original data is hosted there.

Tabled in late August 2026, the text was adjourned for lack of examination time at the extraordinary session opened on 25 August 2026. The index measures the infrastructure serving the systems, as observed on the public network, on the date of each reading.

How it is measured

Census
118 systems, constituted from the certificate transparency logs for the public half and from published registers for the financial and health ones. 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 published 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; 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 91.5 % of the census on the site axis.
Method version
Every point carries the method version in force on its date, version 1 today. Read the method
