What happened
On December 15, 2025, Cloudflare released its Radar Year in Review across traffic, AI, adoption, connectivity, security and email security, using a January 1 to December 2, 2025 data window. It reflects the platform's observations rather than a complete census of all networks.
Implications for website operations
Growth can come from people, search crawlers or automated calls, each with different value and cost. Total traffic alone may conceal problems: more crawling can increase origin load, while connectivity failures may reduce volume but raise error rates.
Operational next steps
Segment monitoring by endpoint, user region and request purpose, then correlate success, caching, origin load and conversion. Set explicit policies for search and AI crawlers while keeping intended public content discoverable.
