• In 2025, we observed over 180 Internet disruptions spurred by a variety of causes â 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 â 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. This post is intended as a summary overview of observed and confirmed disruptions and is not an exhaustive or complete list of issues that have occurred during the quarter. • These anomalies are detected through significant deviations from expected traffic patterns observed across our network.

Article Summaries:

  • In Q4 2025, the Internet experienced more than 180 disruptions worldwide, ranging from brief outages to multi‑day failures. Only one government‑directed shutdown occurred-Tanzania’s 26‑hour cut on Oct 29 amid election protests-while numerous cable cuts in Tanzania and Haiti caused widespread connectivity loss. Power failures and extreme weather also disrupted services in several regions, and the Ukraine conflict further strained connectivity there. Technical faults, some acknowledged by providers and others unknown, contributed to the incidents, alongside outages at hyperscaler cloud platforms and Cloudflare that impacted website and application availability. The report notes these events were identified through traffic‑pattern deviations and directs readers to the Cloudflare Radar Outage Center for full details.
