warmup.rocks is live — no more cold CDN edges

A CDN isn't one cache. It's hundreds of independent ones, and most of them are cold. Cloudflare alone runs 300+ data centers, each with its own memory — so your page can be instant in Frankfurt and ice cold in Tokyo, where the first visitor pays the full origin round trip. Across 408,000 measured requests, a miss ran 3.5× slower than a hit.

warmup.rocks fixes that at the edge. On a schedule, it requests your pages from 42 countries across 6 continents, warming 90+ edge locations per pass — then reads the cache-status headers back so you see the real hit ratio per location, per run. Warming without verification is just hoping.

Also shipping today: sitemap auto-discovery (nested indexes resolved before every run), CDN auto-detection for Cloudflare, Fastly, CloudFront, Akamai, bunny.net and CDN77, deploy hooks plus an official GitHub Action, a mobile user-agent pass, and email alerts when a WAF rule blocks a run.

Nothing to install. No plugin, no DNS change. Two free tools with no signup: a multi-location cache checker and a website speed test.
