Monitoring global Internet disruptions throughout the third quarter of 2026 reveals how infrastructure failures, natural events, and governmental mandates affected network access.
Cloudflare Radar provides a unique vantage point, as its global network manages over 20% of web traffic, allowing observation of traffic behavior when connectivity breaks down.
During July through September, the Internet experienced interruptions primarily stemming from failures in supporting systems. Power grids experienced issues in Cuba, Honduras, Guam, Ukraine, and other nations.
Government-directed shutdowns were the most common cause of disruption, largely stemming from testing-related closures in Iraq. Renewed fighting in Ethiopia’s Tigray region highlighted how swiftly connectivity can become entangled with humanitarian crises.
In total, Cloudflare Radar logged 49 incidents across the quarter. Nineteen of these were government-directed closures, eighteen of which involved Iraq's testing schedules. Power failures accounted for 14 events, while natural disasters registered five.
The necessity of electricity remains a critical dependency for the Internet, even though the system is designed to be distributed. When power ceases, essential components like data centers and routers can fail alongside it.
In Cuba, connectivity mirrored the unpredictable nature of an unstable power supply, with four power-related outages observed during the period. Honduras demonstrated that a localized infrastructure failure could impact numerous major service providers nationally.
Geopolitical conflict proves to be a significant catalyst for Internet interruptions. An August 12 drone strike targeting energy facilities in Ukraine caused a ten-hour outage, resulting in a traffic decline up to 95%.
Natural events also caused significant service interruptions. In Colombia, a magnitude 7.4 earthquake led to a four-and-a-half-day service disruption due to damage to fiber-optic infrastructure.
Exam closures in Iraq occurred on a precise schedule, typically lasting between 15 and 90 minutes. "In a video message, Minister Mustafa Sanad, Iraq's Minister of Communication, confirmed the shutdown and vowed to develop a digital system that would eliminate the need for centralized exam distribution and, by extension, the need to shut down Internet access on exam days," stated the Internet Society Pulse.
The recurrence of shutdowns in Ethiopia’s Tigray region, linked to renewed conflict, mirrors past severe restrictions, where the World Health Organization described the previous situation as a “de facto blockade.”
These events underscore that the operational stability of digital platforms is inextricably linked to the physical reliability of underlying power and physical infrastructure.
