That's not enough to catch real global bottlenecks.</p> <p>So I built a free tool that checks your website's Time to First Byte from 114 countries simultaneously.</p> <p>What you get:</p> <ul> <li>Response times across 6 continents</li> <li>Status codes per location</li> <li>Geographic latency breakdown</li> <li>No signup required</li> </ul> <p>What I've learned from running it:</p> <ul> <li>Latency varies way more than people expect. Same site, 200ms in one country, 2s+ in another.</li> <li>A lot of sites return errors in specific regions without the owner knowing.</li> <li>CDN placement is often guessed, not data-driven.</li> </ul> <p>Try it: <a href="https://hostcry.com/tools/ttfb-checker" rel="noopener noreferrer">https://hostcry.com/tools/ttfb-checker</a></p> <p>Would love feedback from anyone running a global SaaS — is this data useful? What would make it more actionable?</p> webdev webperf performance saas
