Could the internet split into country-specific internets?

Yes — the internet can become more country-specific, and that trend is already underway. A full breakup into totally separate national internets is possible in theory, but it’s costly and unlikely to happen cleanly.

What’s happening instead is a “splinternet”: countries keep some access to the global internet while adding more controls, local routing, censorship, data-localization rules, and platform restrictions.

Examples

• China: major foreign services are blocked or heavily restricted.
• Russia: has tested ways to keep domestic services running while isolating more traffic.
• Iran: can sharply restrict international traffic while preserving some internal services.
• Europe and other regions: privacy and data-transfer rules make cross-border data flows more regulated.

Why this is growing

• Governments want more control over speech, security, and surveillance.
• Some countries require data to stay local.
• Geopolitical rivalry is pushing different tech standards and app ecosystems.

Why a total split is hard
The internet’s core protocols and much of its infrastructure are still shared globally, and trade, finance, and communication depend on that connectivity.

Bottom line: more fragmented and country-shaped internet, yes; a clean global breakup, unlikely.
