Cloudflare’s Q3 2025 Internet Disruption Summary: Key Insights
Cloudflare has recently released its Q3 2025 Internet Disruption Summary, providing a comprehensive overview of significant Internet outages that occurred from July to September 2025. The report details various connectivity incidents worldwide, with a notable focus on disruptions affecting the Middle East and Africa (MEA) region. Factors such as infrastructure challenges, power outages, and government-imposed restrictions heavily contributed to these incidents.
Global Internet Outages
This quarter highlighted how various factors can intertwine to disrupt Internet connectivity across the globe. Cloudflare’s Radar platform continually tracks Internet traffic patterns, revealing that outages stemmed from government-mandated shutdowns, damage to fiber and submarine cables, power failures, cyberattacks, and technical issues. The findings emphasize the increasing complexity and vulnerability of the global Internet infrastructure.
Significant Disruptions in the MEA Region
During the third quarter of 2025, the MEA region faced several notable interruptions:
United Arab Emirates
On July 17, a major incident occurred when a submarine cable was cut, leading to a sudden 28% decrease in Internet traffic. This disruption affected multiple Internet Service Providers (ISPs) and significantly impacted international routing paths. Fortunately, traffic began to recover gradually over the next few hours as rerouting measures were implemented.
Egypt
Egypt also faced challenges when a fire broke out at a significant telecommunication facility in Cairo. This incident disrupted services for several Internet providers, resulting in widespread connectivity issues across parts of the country.
Government Shutdowns in Sudan, Syria, Iraq, and Afghanistan
In several nations, including Sudan, Syria, Iraq, and Afghanistan, governments enforced Internet shutdowns, often during crucial national examination periods or events tied to security. This trend demonstrates the ongoing use of Internet controls during politically sensitive times.
Tanzania
A nationwide power outage in Tanzania marked another significant disruption, leading to a dramatic decline in Internet traffic. This incident underscores the vulnerability of digital services in developing markets, where infrastructure may be lacking.
Yemen
In Yemen, a targeted cyberattack was detected that disrupted international connectivity routes. This malicious act temporarily isolated several networks from accessing the global Internet.
Other Major Disruptions Worldwide
Beyond the MEA region, numerous other consequential disruptions were documented:
-
Venezuela and Parts of Asia: Government-imposed shutdowns were noted, further impacting connectivity in these regions.
-
Pakistan and Southeast Asia: Issues related to submarine and terrestrial cables affected connectivity, highlighting the fragility of infrastructure in these areas.
-
Cuba, Gibraltar, and the Czech Republic: Several data center and power-related outages were reported, resulting in service interruptions.
-
China: There were technical anomalies, including disruptions to Starlink services, alongside unusual activity from the Great Firewall, which involved injecting forged TCP resets that obstructed encrypted traffic.
Cloudflare Radar: Enhancing Internet Transparency
Cloudflare’s Radar platform has evolved to offer rich regional traffic insights, empowering researchers, media professionals, and network operators to analyze outages based on network type, geographical location, and service category. This enhanced visibility aids in identifying patterns related to latency, DNS behavior, and routing changes during disruptive events.
The Q3 2025 Internet Disruption Summary represents Cloudflare’s commitment to foster a more resilient, secure, and transparent Internet. For those interested, the full report, along with datasets and interactive charts, is accessible through the Cloudflare Radar Outage Center and on the official Cloudflare Blog.
