About this network

ATI-TN — the Agence Tunisienne d'Internet, Tunisia's state internet agency and the operator of the country's national IP backbone.

What it's used for

• National backbone and upstream connectivity for Tunisian ISPs, universities and public institutions, along with hosting and domain services run by the agency.

Notable

• A government network in the truest sense: ATI is a public agency, and for years it was the mandatory international gateway through which essentially all Tunisian internet traffic passed.
• That chokepoint position made ATI the technical instrument of national filtering under the pre-2011 regime, a role widely mocked at the time as "Ammar 404". The agency was restructured after the 2011 revolution and the filtering apparatus dismantled.

Interesting

• A single agency holding both the national backbone and the country's early ASN is a common shape for states that brought the internet in through one door in the mid-1990s.
