If 2024 was the year the world woke up to Generative AI, 2025 was the year the internet itself began to change shape to accommodate it.
According to the newly released Cloudflare Year in Review 2025, global internet traffic grew by a robust 19%, accelerating slightly from the previous year. But the raw numbers tell only half the story. Sitting at the nexus of a vast portion of the world’s web traffic, Cloudflare’s data reveals a digital landscape in flux, defined by a transition from human browsing to automated action, from Western-centric infrastructure to Asian dominance, and from connectivity as a given to a contested political tool.
From the rise of autonomous agents to India’s quiet infrastructure revolution, here are the five epic shifts that defined the internet in 2025.

For years, the internet was built for human eyes. In 2025, it became a workspace for machines. The most explosive finding in the report is a staggering 15x surge in traffic from “AI agents” performing “User Actions.”
Unlike the passive chatbots of yesteryear (like early ChatGPT) that simply retrieved information, these new agents are designed to do things – book flights, negotiate purchases, and navigate complex workflows on behalf of users. While traditional crawlers like Googlebot still dominate the indexing landscape (viewing 12% of all sampled pages), this massive spike in agentic traffic suggests we are witnessing a fundamental architectural shift: the web is evolving from a library for humans into an operating system for AI.
While many Western nations struggle to upgrade legacy networks, India has effectively leapfrogged into the future. The 2025 report cements India’s position as the undisputed global leader in IPv6 adoption, with a massive 67% adoption rate.
To put this in perspective, the global average hovers around 33%. Driven by a mobile-first ecosystem and aggressive 5G deployment, India has bypassed the transitional technologies that bog down other regions. By embracing the modern protocol necessary to connect billions of devices, India hasn’t just caught up to the developed world, it has built a more scalable, future-proof internet foundation than almost anywhere else on Earth.

For a decade, the logic of cyberwarfare was simple: follow the money. Hackers targeted banks, crypto exchanges, and gaming giants. In 2025, the crosshairs shifted.
For the first time, civil society and non-profit organizations became the number one target for cyberattacks globally. Fueled by emerging threats like the massive Aisuru botnet, attackers unleashed record-breaking “hyper-volumetric” DDoS strikes. The motivation has moved from financial extortion to geopolitical suppression, with cyber weapons increasingly used to silence dissent and disrupt humanitarian aid rather than just steal data.
Internet outages used to be stories about severed undersea cables or faulty hardware. In 2025, the biggest threat to connectivity came from governments.
Cloudflare observed 174 major internet disruptions throughout the year. Disturbingly, nearly half of these were traced to government-mandated shutdowns. Nations are increasingly treating the internet as a switch to be flipped to control populations – cutting connectivity to prevent cheating during national exams or to quell civil unrest. The “internet blackout” has evolved from an accidental bug to a deliberate feature of state control.
Finally, 2025 was the year satellite internet shed its reputation as a niche luxury for the wealthy or remote. Traffic from Starlink doubled year-over-year as the service expanded into over 20 new regions.
This surge contributed significantly to the overall growth in global traffic, signaling that Low Earth Orbit (LEO) connectivity has become a critical component of the global internet backbone. For millions of users, the sky is no longer the limit, it’s the access point.
