"Altogether, Cloudflare reported in its 2025 fourth quarter analysis that it observed more than 180 internet disruptions worldwide over the course of 2025, ranging from short, localized incidents to multiday nationwide outages. The most dramatic outages involved physical infrastructure failures, especially submarine cables and national power grids. For example, in Haiti, Digicel suffered two separate international fiber cuts in October and November, pushing traffic on its network close to zero during one incident and triggering multi‑hour outages until repairs were completed."
"Power problems drove country‑scale disruptions in the Dominican Republic and Kenya. For the Caribbean country, transmission line failure on Nov. 11 knocked out electricity and cut internet traffic by nearly 50% until the grid was mostly restored around 2:20 a.m. the following day. Later, a Kenya‑Uganda interconnection issue triggered a Kenyan blackout on Dec. 9, which depressed national traffic by up to 18% for nearly four hours."
More than 180 internet disruptions occurred worldwide in 2025, ranging from short localized outages to multiday nationwide failures. Major causes included physical infrastructure damage such as submarine cable cuts and national power grid problems, as well as cloud-provider outages and traditional network misconfigurations. High-profile cloud failures affected services from Azure, Google Cloud, Cloudflare, and a severe AWS collapse in October. Country-scale incidents included Digicel's international fiber cuts in Haiti, a transmission line failure that halved internet traffic in the Dominican Republic, and a Kenya blackout following a Kenya‑Uganda interconnection issue. Government-ordered shutdowns declined compared with earlier in the decade.
