Disallow: /Frequently Asked Questions
Should I Block Cloudflare SpeedTest?
Only if nobody you work with uses it. Cloudflare SpeedTest is the kind of tool a team points at its own site for uptime checks, performance tests, and audits. If someone on your team relies on it, blocking it silently breaks their monitoring. Almost none of the top websites we track have robots.txt rules for Cloudflare SpeedTest right now.
Does Cloudflare SpeedTest Respect Robots.txt?
No. Cloudflare SpeedTest is not expected to honor robots.txt, so a disallow rule only states your preference. Enforce the block with firewall or server rules, then confirm in Agent Analytics that its requests actually stop.
Does Cloudflare SpeedTest Access Private Content?
Only if its owner sets that up. Monitoring tools check whatever they are configured to check, which can include staging sites and private health endpoints when a team grants access. Uninvited, Cloudflare SpeedTest sees only public pages.
Why Is Cloudflare SpeedTest Visiting My Website?
Someone pointed Cloudflare SpeedTest at your site, most likely your own team. Uptime monitors, performance testers, and audit tools only visit the sites they are configured 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 regular checks of the same pages or endpoints, often minutes apart. Keep in mind that Cloudflare SpeedTest doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
