Cloudflare Year In Review: AI Bots Crawl Aggressively, Post-Quantum Encryption Hits 50%, Go Doubles
Cloudflare, Wednesday, December 31st, 2025
Cloudflare has recently published the sixth edition of its Radar Year in Review. The results reveal 19% yearly growth in global internet traffic, Googlebot dominance, increasing crawl-to-refer ratios, and broad adoption of post-quantum encryption. Over 20% of automated API requests were made by Go-based clients, almost doubling adoption over the previous year.
Leveraging data from the widespread Cloudflare infrastructure, including anonymized query data for traffic to the 1.1.1.1 public DNS resolver, the yearly report analyzes the disruptions, advances, and metrics that defined the Internet in 2025. The review is organized into different sections (traffic, AI, adoption & usage, connectivity, security, and email security) and uses the same methodologies as previous years.
With global traffic growing 19% during the year and Google and Facebook still the most popular services, the report highlights significant growth for Starlink, up 2.3x year-over-year.
