Decoding the 2025 Internet
The Cloudflare Radar report provides a valuable overview of internet trends, especially regarding the explosive growth of AI and the increasing prevalence of post-quantum encryption. The data-driven approach, utilizing Cloudflare's extensive network, offers a unique perspective on global traffic patterns, bot activity, and security threats. The insights into the impact of government-directed internet shutdowns and the growth of Starlink are particularly noteworthy. However, the report is limited by its reliance on Cloudflare's specific vantage point, potentially missing trends not visible within their network. Additionally, while comprehensive, the sheer volume of data might overwhelm some readers, potentially requiring more focused analyses on specific areas.
Key Points
