The first quarter of 2026 saw a dramatic rise in internet disruptions worldwide, driven by government-imposed shutdowns, infrastructure failures, and geopolitical conflicts. Unlike the same period in 2025—which observed no government-directed blackouts—Q1 2026 featured prolonged outages in Uganda and Iran. Power grid collapses, military activities, severe weather, and technical glitches compounded the challenges. This list covers ten notable incidents that cut off millions from digital connectivity, highlighting the fragility of today's internet. While not exhaustive, these examples underscore the diverse causes of disruptions—from deliberate policy to natural disasters. For a deeper dive, the Cloudflare Radar Outage Center tracks additional anomalies. Here's what you need to know.
1. Government-Directed Shutdowns Return in Force
After a quiet start to 2025, government-ordered internet blackouts made a stark comeback in Q1 2026. Authorities in Uganda and Iran implemented blanket shutdowns, citing election security and public order. These actions cut off entire nations from the web for days or weeks, affecting daily life, business, and access to information. The trend marks a worrying reversal, raising concerns among digital rights advocates. Unlike technical failures or weather events, these shutdowns are intentional and politically motivated. They demonstrate how quickly connectivity can be weaponized, leaving citizens in the dark and disrupting global communications.

2. Uganda's Pre-Election Blackout
On January 13, 2026, three days before the presidential election, Uganda ordered a nationwide internet shutdown. The Uganda Communications Commission (UCC) instructed mobile operators to suspend public access at 18:00 local time. Traffic at the Uganda Internet Exchange Point (UIXP) plummeted from 72 Gbps to just 1 Gbps. Cloudflare data confirmed near-zero traffic through January 17, when partial restoration began after President Yoweri Museveni secured a seventh term. Full connectivity resumed on January 26, with telecoms MTN Uganda and Airtel Uganda announcing the lift. The shutdown drew lawsuits and criticism from groups like CIPESA, as it mirrored a similar 2021 blackout despite earlier government promises otherwise.
3. Iran's Prolonged Internet Outage
Iranian citizens endured a sweeping internet blackout during Q1 2026, part of a pattern of government restrictions amid civil unrest. While exact dates and reasons remain opaque, the shutdown was clearly state-directed. Internet connectivity dropped sharply for days, impacting everything from banking to social media. Iran has a history of such measures, often to suppress protests or control information. The Q1 2026 blackout was among the longest in recent years, affecting millions and drawing condemnation from human rights organizations. The disruption highlighted Iran's reliance on centralized control over internet infrastructure, leaving its population without access to global networks for extended periods.
4. Cuba's National Power Grid Collapses Three Times
Cuba experienced three separate collapses of its national electrical grid in Q1 2026, each causing widespread internet outages. The island's aging infrastructure, combined with fuel shortages, led to cascading failures. With power down, ISPs and cell towers lost backup, plunging much of the population offline for hours or days. These blackouts disrupted daily life, from work to healthcare. Though not government-directed, they exposed Cuba's vulnerability to energy crises. The repeated failures underscore the link between reliable electricity and internet access. For Cubans, connectivity remains a luxury dependent on a fragile power system struggling under economic pressures.
5. Ukraine: Military Action Disrupts Connectivity
Ongoing military conflict in Ukraine continued to sever internet links in Q1 2026. Fighting damaged physical infrastructure like fiber optic cables and power lines, leading to intermittent outages in frontline regions. Both civilian and military communications were affected, hampering emergency services and daily life. Cloudflare data showed traffic dips in areas near active combat. While Ukraine's internet has proven resilient, these disruptions are a stark reminder of war's toll on digital networks. The attacks on infrastructure also threaten global data flows, as Ukraine hosts key internet exchange points for Eastern Europe.
6. Middle East Hyperscaler Infrastructure Hit
Military action in the Middle East during Q1 2026 impacted cloud infrastructure operated by major hyperscalers like AWS, Google Cloud, and Microsoft Azure. These providers host critical services for governments and businesses across the region. The disruption likely stemmed from airstrikes or sabotage near data centers, though specifics remain classified. Traffic drops were observed, affecting everything from streaming to enterprise apps. This incident highlights how geopolitical conflict can ripple through the backbone of the internet, threatening global digital services. It also shows the vulnerability of centralized cloud architecture in volatile regions.

7. Portugal: Severe Weather Knocks Out Internet
In February 2026, severe storms and flooding hit Portugal, causing widespread power outages and internet disruptions. Extreme wind and rain damaged overhead lines and submerged key network nodes. ISPs reported service interruptions in several regions, with restoration taking days. This event underscores how natural disasters can immobilize digital infrastructure, even in developed Europe. Emergency services struggled to coordinate as communications failed. For many, the internet became a casualty of climate-driven weather. The Portuguese case reminds us that the internet is not immune to the elements, and resilient design is crucial.
8. Republic of Congo: Cable Damage Brings Outage
In Q1 2026, fiber optic cable damage disrupted internet connectivity in the Republic of Congo. The cause was likely construction or accidental severing, although specifics remain unclear. The break cut off major towns including Brazzaville for several hours, affecting banking, government, and personal communications. Repairs required specialized teams, highlighting the fragility of land-based cables in regions with limited redundancy. This event is a textbook example of how a single cut can cripple a nation's internet, especially in countries reliant on limited backbone links. The disruption forced many to rely on satellite networks as a stopgap.
9. United States: Verizon Wireless Outage
In March 2026, a technical problem hit Verizon Wireless, causing widespread service interruptions across the United States. Customers lost mobile data and voice services for several hours, affecting millions. The issue was traced to a software update glitch in the core network, not external attack. This outage highlighted the vulnerability of major telecom providers to internal errors. For businesses and individuals reliant on Verizon, it disrupted work, travel, and emergency calls. The incident prompted scrutiny of carrier backup systems and led to calls for transparent reporting. While resolved quickly, it underscored the fragility of U.S. mobile networks.
10. Guinea and United Kingdom: Unknown Issues Hit Providers
Brief connectivity issues struck providers in Guinea and the United Kingdom in Q1 2026, though causes remain unknown. In Guinea, mobile and fixed-line users lost service for hours; in the UK, a fiber ISP experienced a similar blip. No official explanations were released, but network equipment failures or routing problems are suspected. These events, though short-lived, illustrate that unexplained outages can happen anywhere. They also highlight the need for robust monitoring and transparency from ISPs. For customers, such hiccups are frustrating reminders that even stable networks can falter without warning.
Conclusion
Q1 2026 was a turbulent quarter for global internet connectivity. From deliberate government shutdowns in Uganda and Iran to power grid collapses in Cuba and war-related damage in Ukraine and the Middle East, the internet's fragility was on full display. Severe weather, cable cuts, technical glitches, and mysterious failures added to the mix. These incidents, while not exhaustive, reveal the diverse threats to our digital world. As reliance on the internet deepens, understanding these vulnerabilities becomes critical for building a more resilient global network. The Cloudflare Radar Outage Center continues to monitor such events for deeper insights.
