Cable Cuts, Storms, And DNS: A Look At Internet Disruptions In Q4 2025
Cloudflare, Monday, January 26th, 2026
In 2025, we observed over 180 Internet disruptions spurred by a variety of causes - some were brief and partial, while others were complete outages lasting for days. In the fourth quarter, we tracked only a single government-directed Internet shutdown, but multiple cable cuts wreaked havoc on connectivity in several countries.
Power outages and extreme weather disrupted Internet services in multiple places, and the ongoing conflict in Ukraine impacted connectivity there as well. As always, a number of the disruptions we observed were due to technical problems - with some acknowledged by the relevant providers, while others had unknown causes. In addition, incidents at several hyperscaler cloud platforms and Cloudflare impacted the availability of websites and applications.
