Frequently Asked Questions
Should I Block Cloudflare SpeedTest?
Only if no one on your team relies on it. Cloudflare SpeedTest may support uptime monitoring, performance tests, or audits. Blocking it without checking first can silently disrupt those workflows. Almost none of the top websites we track currently have robots.txt rules for Cloudflare SpeedTest.
Does Cloudflare SpeedTest Follow Robots.txt Rules?
No. Cloudflare SpeedTest is not expected to follow robots.txt directives, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Does Cloudflare SpeedTest Access Private Content?
Only when configured with access. A team may grant Cloudflare SpeedTest credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
Why Is Cloudflare SpeedTest Visiting My Website?
Someone, most likely on your own team, configured Cloudflare SpeedTest to check your site. Uptime monitors, performance testers, and audit tools visit only the sites or endpoints they are told to watch.
How Can I Tell if Cloudflare SpeedTest Is Visiting My Website?
Agent Analytics tracks Cloudflare SpeedTest visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "Cloudflare SpeedTest". Look for repeated checks of the same pages or endpoints at regular intervals. Because Cloudflare SpeedTest does not publish a verification method, any client can claim its identity and a log match is only a clue.
