Pro Tips
Use DNS lookup to verify DNS propagation
After updating DNS records, use the DNS Lookup tool to verify that changes have propagated. Cloudflare DNS resolvers update quickly, making this a reliable check.
Check SSL before it expires
Use the SSL Checker regularly to monitor certificate expiry dates. Set a reminder when days remaining drops below 30.
Verify security headers on your websites
Use the HTTP Headers tool to check that your site has proper security headers: HSTS, CSP, X-Frame-Options, and Content-Type-Options.
Use port scanning to audit your servers
Scan your own servers to verify that only expected ports are open. Close unused ports to reduce attack surface.
Compare ping times from different locations
The Ping tool measures latency from your browser. Use it to compare response times to different CDN endpoints or server regions.
