Ping & response time
Three-run breakdown of DNS, TCP connect, and HTTP timing from BuildSpace—closer to real web stacks than classic ICMP ping.
What latency / “ping” here means
True ICMP ping is often unavailable from application platforms and is a poor stand-in for “can users load my site?” anyway. What usually matters for web stacks is DNS resolution time, TCP connect time to the right port, and HTTP round-trip time.
We run three back-to-back samples of each phase so you see variance—not a single lucky packet. That matches how engineers and AI assistants reason about “noisy” networks vs steady regressions.
Use it to compare before/after a DNS or CDN change, or to explain why “the server is up” but the page still feels slow.
How this tool works
Short technical summary of what runs on our servers when you click the button.
For your URL we measure resolver latency, TCP connect to the implied port (443 for https, 80 for http), and a small HTTP request with the same redirect-safe logic as our header checker.
We report per-run values plus min, max, and average so single outliers are visible.
Only URLs that pass our public-host checks are measured—no internal network timing probes.
