Government internet shutdowns disrupt networks, says Cloudflare data

New data from Cloudflare suggests such shutdowns remain a recurring feature of the global internet landscape. The company’s Q3 2025 internet disruption summary highlights several government-directed connectivity disruptions across multiple regions, demonstrating how state intervention can abruptly reshape national traffic flows.

For carriers and internet infrastructure providers, these disruptions raise practical questions around network stability, interconnection and traffic management.

Shutdowns increasingly visible in network data

Because of the scale of its global network, Cloudflare can detect connectivity anomalies through sharp deviations in expected traffic patterns. The company publishes these observations through its Cloudflare Radar platform, which monitors traffic across its infrastructure and identifies outages and anomalies.

In the third quarter of 2025, several disruptions were attributed to government action rather than technical failure.

One example came from Sudan, where repeated daily traffic drops were observed between 12:00 and 15:00 UTC from July 7 to July 10. The disruptions affected multiple networks including Sudatel, SDN Mobitel and MTN Sudan. The timing aligned with national secondary school examinations, leading researchers to conclude that authorities were likely enforcing temporary internet shutdowns to prevent exam cheating.

Short, repeated outages tied to exam periods have become a familiar pattern in several countries. However, even when they are temporary, such shutdowns still represent abrupt national-scale changes in traffic levels.

For operators and IXPs connected to affected markets, this can mean sudden traffic collapses followed by equally sharp recoveries once connectivity returns.

When regulation becomes a network event

Another case highlighted in the report demonstrates how regulatory action can effectively remove an operator from the internet.

In August 2025, Venezuelan provider SuperCable ceased operations after the country’s telecommunications regulator revoked its licence. According to Cloudflare’s analysis, traffic to the network disappeared within roughly 30 minutes of subscribers receiving notice that service was ending. Connectivity remained offline through the rest of the quarter.

Unlike temporary shutdowns, such regulatory actions can have longer-term effects on connectivity ecosystems. Removing a provider from the market can force customers to migrate to other networks, altering traffic distribution and potentially increasing load on competing operators.

For infrastructure providers, this kind of disruption also raises questions around redundancy and market concentration in national connectivity environments.

Nationwide shutdowns and infrastructure impact

The report also highlights a more extensive shutdown in Afghanistan during September 2025.

Authorities ordered the shutdown of fibre-optic connectivity across multiple provinces as part of a campaign aimed at preventing what officials described as “immorality”. At its peak, as many as 15 provinces experienced disruptions, affecting online services including education, commerce and government systems.

Later that month, Afghanistan experienced a brief interruption to wired internet services before a complete nationwide shutdown temporarily took the country offline. Connectivity was restored roughly two days later.

Events like these illustrate the degree to which modern national connectivity depends on a relatively small number of core infrastructure nodes.

When authorities intervene at the backbone level, the effects can cascade across multiple networks simultaneously.

A growing operational consideration

While politically motivated shutdowns have occurred for years, they are increasingly visible through network measurement platforms and traffic monitoring tools.

For telecom operators and internet infrastructure providers, that visibility underscores an important shift: shutdowns are no longer rare anomalies but recurring events that can affect network behaviour across entire regions.

Even temporary outages can influence traffic engineering, peering utilisation and CDN performance. Sudden drops in traffic from a country may alter routing decisions or shift load to neighbouring networks and transit providers.

From a planning perspective, this means shutdowns are becoming another variable in the broader resilience equation that operators must consider alongside fibre cuts, power failures and cyber incidents.

Ultimately, government-directed shutdowns sit at the intersection of policy and infrastructure.

States may view them as tools for enforcing regulation or controlling information flows. But for the networks that carry global traffic, they represent sudden and often unpredictable disruptions.
