The first quarter of 2026 witnessed a striking array of internet outages worldwide, ranging from government-ordered blackouts to infrastructure failures. This article breaks down the ten most significant disruptions, highlighting how political decisions, technical issues, and natural events each played a role in cutting off connectivity. Based on data from Cloudflare and other sources, these incidents underscore the fragility of our global network.
1. Uganda’s Election-Linked Shutdown
In January, Ugandan authorities imposed a nationwide internet blackout ahead of the presidential election. Starting on January 13 at 18:00 local time, mobile operators were instructed to suspend public access, citing the need to curb misinformation and fraud. Traffic at the Uganda Internet Exchange Point plummeted from 72 Gbps to just 1 Gbps, and Cloudflare observed near-zero traffic until partial restoration on January 17 after President Museveni was declared winner. Full services resumed on January 26, but the shutdown sparked lawsuits and criticism from digital rights groups, echoing a similar move during the 2021 election despite earlier promises of no repeat.
2. Iran’s Prolonged Internet Blackout
Iranian citizens endured an extended government-directed shutdown during Q1 2026, continuing a pattern of periodic restrictions. The blackout, which began in late January, cut off access to most online services, including social media and messaging apps. Cloudflare data showed a dramatic drop in traffic, with only limited connectivity remaining for government-approved sites. The move was widely seen as an effort to suppress dissent amid ongoing protests. Unlike Uganda, where restoration was announced, Iran’s blackout lingered for weeks, highlighting the regime’s tight grip on internet infrastructure.
3. Cuba’s Repeated Power Grid Collapses
Cuba faced three separate collapses of its national electrical grid in Q1 2026, each triggering widespread internet outages. The first occurred in February, followed by two more within a month, crippling connectivity across the island. With limited backup power, most mobile towers and fiber networks went dark, leaving citizens reliant on offline communication. The grid failures were attributed to aging infrastructure and fuel shortages, exacerbating the country’s ongoing economic crisis. Each collapse lasted for days, making this the most consistent disruption in terms of frequency.
4. Conflict-Related Disruptions in Ukraine
Military operations in Ukraine continued to disrupt internet connectivity during Q1 2026, with shelling and cyberattacks targeting telecom infrastructure. Several regions experienced intermittent outages, particularly in frontline areas. Cloudflare detected traffic fluctuations near conflict zones, with some providers forced to reroute services. The disruptions added to the challenges faced by civilians and emergency services, highlighting how war directly impacts digital access.
5. Hyperscaler Cloud Disruptions in the Middle East
In the Middle East, military action affected hyperscaler cloud infrastructure, causing widespread outages for businesses and users dependent on platforms like AWS and Google Cloud. The incident, linked to airstrikes in the region, disrupted data centers and led to service degradation for several hours. This event underscored the vulnerability of global cloud services to regional conflicts, as even distant users experienced slowdowns due to rerouted traffic.
6. Severe Weather Knocks Out Portugal
Severe storms in Portugal during February caused widespread damage to power lines and internet infrastructure. Heavy winds and flooding disrupted connectivity for thousands of users, particularly in rural areas. Cloudflare data showed a sharp dip in traffic, with restoration taking several days as repair crews worked to restore services. The event highlighted how extreme weather remains a potent disruptor of digital life, even in developed nations.
7. Cable Damage in the Republic of Congo
A fiber optic cable break in the Republic of Congo in March cut off internet access for major cities, including Brazzaville and Pointe-Noire. The damage, likely from construction or environmental factors, required extensive repairs. Traffic dropped to near zero for several days, affecting businesses and government services. This incident emphasized the reliance on a few undersea and terrestrial cables for connectivity in many African nations.
8. Verizon Wireless Technical Glitch
In the United States, a technical problem hit Verizon Wireless in late February, causing a nationwide outage for several hours. Users reported inability to make calls or use mobile data, with Cloudflare observing a sharp drop in traffic from the carrier. Verizon attributed the issue to a software update error and resolved it within a day. Though brief, the outage affected millions and drew attention to the fragility of major telecom networks.
9. Unknown Issues in Guinea
Guinea experienced a mysterious internet outage in March, with connectivity briefly disrupted for customers of multiple providers. Cloudflare detected a steep traffic decline but could not pinpoint the cause—whether technical failure or regulatory action. The disruption lasted less than 24 hours but highlighted the challenges of identifying root causes in regions with limited transparency. Local users turned to alternative networks like satellite services to stay online.
10. Unknown Issues in the United Kingdom
Similarly, the United Kingdom saw a brief, unexplained outage affecting customers of several ISPs in Q1 2026. Traffic data from Cloudflare showed a sudden dip, quickly recovering. The cause remained unknown, possibly a routing error or hardware fault. While minor compared to other events, it served as a reminder that even well-connected nations are not immune to unexpected glitches.
In conclusion, Q1 2026 demonstrated the diverse threats to internet reliability: from deliberate government actions in Uganda and Iran, to infrastructure failures in Cuba, conflict in Ukraine and the Middle East, natural disasters in Portugal, and technical glitches in the US and beyond. Each incident offers lessons for improving resilience—be it through backup power, redundant cables, or international pressure against shutdowns. As our dependence on the internet grows, understanding these disruptions is key to building a more robust global network.
