The Layer You Don’t See: Notes from Inside Kyrgyzstan’s Internet Backbone

Most conversations about connectivity in Kyrgyzstan happen at the household level — bars on a phone, the price of a monthly plan, whether a school’s Wi-Fi is up that morning. Almost none of those conversations reach the layer that sits underneath: the cables that physically cross the border, the exchanges where domestic traffic is routed without leaving the country, and the data centres where, increasingly, the records of public life are kept. It is the part of the network citizens never see, and it is the part that decides what is possible at every layer above it.

I have a direct reason to start this piece at the exchange rather than at the tower. In 2017 I co-founded KG-IX, the Bishkek Internet Exchange, and helped run it for four years before selling it in 2021. Most of what I will say in the rest of this piece about how the country’s traffic actually moves is the view from inside that work — peering agreements with operators, the slow build-up of domestic exchange capacity, the handful of meetings where the question of where Kyrgyzstan’s bytes physically rest is settled in the most ordinary technical language.

By 2024, KG-IX handled around 92% of domestic exchange traffic; a smaller second exchange, SR-IX, picked up the remaining 8%. Together, the two of them kept approximately a quarter of the country’s internet activity from having to leave Kyrgyzstan at all. That is, in plain terms, what a working internet exchange does. It is also why an exchange — and not a mobile tower — is the right starting point for any honest account of where the country’s connectivity actually lives.

What the exchange actually localizes

The work that takes up most of an internet exchange’s day is not the traffic that obviously belongs in-country. It is the international content — the platforms hosted somewhere else that nearly everyone in Kyrgyzstan uses every day. Take an ordinary case. One iOS update for an iPhone can run between 5 and 8 gigabytes. Multiplied across a country full of devices, that single update — pushed out within the same week to most users — is a serious chunk of national bandwidth. Without local infrastructure to absorb it, every one of those gigabytes has to travel into the country across a paid international transit link. The cost shows up on the ISP’s books, and a slower experience shows up on the user’s phone.

This is the role a content-delivery network (CDN) plays at an internet exchange. The platform hosts a node — a server — locally, alongside the IXP. The first time a piece of content (an iOS update, a Reels video, a TikTok clip) is requested in Kyrgyzstan, it crosses the border once and is cached. From that point on, every subsequent request inside the country is served from the local node — at local latency, at no additional international-transit cost. The cost curve flattens, the latency falls, and the user experience improves without anyone above the network layer having to do anything.

Over four years at KG-IX, this was the most consequential part of the work. We brought in CDN nodes for Apple, for Meta (which covers Facebook, Instagram, and the rest of that family), and entered talks that eventually brought TikTok content into Kyrgyzstan locally as well. None of these are visible to the end user. They simply mean that an iPhone update finishes faster, that an Instagram reel loads without buffering, that a TikTok feed scrolls cleanly on a 4G connection in Naryn — and that the ISPs delivering that experience are not paying international rates for traffic that no longer needs to cross a border.

The model travels: Fergana, Uzbekistan, and the DNS layer

Internet exchanges have a regional logic. Once one works, the next question is where else the same architecture would change the latency picture. The Fergana valley — the dense, populous corner of Central Asia stretched across the borders of Kyrgyzstan, Uzbekistan, and Tajikistan — was an obvious candidate. Through the Internet Society Kyrgyz Chapter (ISOC KG), between 2019 and 2021, we tried to launch a Fergana Internet Exchange Point to bring the same kind of localisation to that region. It ran into the economic conditions of the COVID-19 period and did not get past the early phase. The need it was set up to address has not gone away.

The same model was, however, taken across the next border. I helped build SNS-IX in Uzbekistan — the country’s first independent internet exchange point — along the same lines as KG-IX. The detail matters: an exchange founded outside the structure of a single dominant operator is, by design, the building block of a more competitive and resilient network. Where it works, it is one of the quieter routes to digital sovereignty.

The same regional work extended below the exchange layer, into the DNS — the part of the internet that turns a name people type into the numerical address a machine can route to. Every page load, every app launch, begins with a DNS query. If those queries have to leave the country to be resolved, every site loads slower than it needs to, and the country’s name resolution depends on infrastructure it does not control. To address this, we brought a set of internationally significant DNS services into Central Asia for the first time: Quad9 (a privacy- and security-focused public resolver), and the F-Root and I-Root name-server instances — two of the thirteen root servers at the very top of the DNS hierarchy. Local root-server instances mean DNS queries that previously had to traverse to Europe or beyond now resolve in milliseconds, in-country, on infrastructure that mirrors the global root system.

How the country actually connects out

Kyrgyzstan is landlocked. There is no undersea cable landing on its territory; everything international has to cross a land border. The bulk of the country’s bandwidth — well above 1 Tbps in aggregate — moves across roughly ten ISPs running cross-border fibre links. Kazakhstan is the primary transit country, with Russia second. Most of what a user in Bishkek loads from Google, Meta, or any other foreign service has, in physical terms, made the journey north and west across the Kazakh steppe before turning back south on its return.

The story underneath that traffic mix has been changing. Russia remains the largest transit corridor for now, but content demand is moving away from Russian-language sources and toward platforms hosted in Kazakhstan, Uzbekistan, and Europe. By a measurable performance check, Bishkek already reaches Google’s Finnish data centre faster than it reaches Hong Kong. The cable map and the content map are slowly diverging.

Transcaspian: the route that changes the geography

The most consequential change to Kyrgyzstan’s backbone is not a domestic project. It is the planned Transcaspian fibre-optic line, expected for 2026, which would give the country a direct corridor across the Caspian to Europe — a path that does not depend on Russian transit. For a country whose international traffic has been routed primarily through Russia for most of the post-Soviet period, this is a quiet but significant reorientation. It is one of the few infrastructure projects in the region where a piece of cable rewrites a piece of geopolitics.

That said, more than 80% of the top-1,000 most visited websites accessed from Kyrgyzstan are hosted outside the country. Whatever the route, the country remains profoundly dependent on the ability to reach servers somewhere else. Transcaspian changes where the country reaches them from, not whether it has to.

Where the country’s data physically lives

Inside the country, two Tier-3 data centres currently carry most of what could be called domestic cloud capacity. The NSP data centre, owned by Kyrgyz founders and funded through the Kyrgyz-Russian Development Fund, opened in 2018. The National Bank data centre opened in 2019. Together, they remain a small footprint by any regional comparison — but they are the footprint that a digital state has to grow from.

The next layer is the government G-Cloud platform, planned under the World Bank’s Digital CASA project for launch by May 2025. G-Cloud is the piece that, once running, lets ministries and state agencies host services on infrastructure that the state itself controls — rather than on commercial or foreign-hosted platforms. It is the technical precondition for almost every claim a digital government wants to make about residency, security, and continuity of public records.

Layer	What it is	2024 status
Internet exchanges (IXPs)	KG-IX (92%) + SR-IX (8%); 1 idle exchange	~230 Gbps total capacity; ~25% of traffic stays domestic
Tier-3 data centres	NSP (2018, KG founders, Kyrgyz-Russian Development Fund); National Bank (2019)	Operational
Government cloud	G-Cloud (Digital CASA)	Planned launch May 2025
International transit	~10 cross-border ISPs; KZ primary, RU secondary	1+ Tbps aggregate
European corridor	Transcaspian fibre line	Expected 2026

What the backbone is doing

Looked at from the household, Kyrgyzstan’s connectivity story is mostly about phones and prices. Looked at from the backbone, it is a quieter and more durable story about routes, exchanges, root servers, and where the country’s data sits when it is not in motion. The mobile network already reaches almost every populated settlement. The work that decides what reaches it, how fast, and through what infrastructure, happens at the layer below.

Above the backbone, every household-level number looks fine. Below it, the work is to keep the country’s traffic — and its name resolution — closer to home.

The next piece in this series turns to a part of the backbone story that actually does reach the household — affordability. Kyrgyzstan’s mobile data prices are among the lowest in the world, and that is not an accident. It is the most underdiscussed part of the country’s digital advantage.
