Ping Test
Measure HTTP or HTTPS reachability and response time from our server runtime.
What This Tool Does
Our ping tool performs an HTTP-based reachability check to a target host and measures the end-to-end response time. It tries HTTPS first and falls back to HTTP when needed. This helps diagnose connectivity issues, compare response times, and verify if a server is online from our server environment. Reported times include DNS resolution, connection setup, and the HTTP request itself, so treat them as HTTP response times rather than raw ICMP ping latency.
Common Use Cases
- Test if a website or server is responding
- Measure HTTP response times to different endpoints
- Diagnose connectivity issues during outages
- Compare response times between different servers
- Verify firewall or security rules allow traffic
Frequently Asked Questions
What is a good response time?
For this HTTP-based check, lower is generally better. Under 100ms is excellent, 100-300ms is solid for many public sites, and higher values can point to geographic distance, slow origin processing, or network issues. Because the measurement includes DNS resolution and connection setup, it will usually be higher than a raw ICMP ping.
Why might the check fail even if the site is working?
Some hosts reject automated probes, require a specific protocol, or rate-limit requests from server environments. Firewalls, redirects, DNS issues, TLS failures, or temporary upstream problems can also prevent a successful result even when the site still works in a browser.
What causes high response times?
High response times can result from geographic distance, DNS delays, network congestion, TLS handshakes, overloaded servers, or issues with intermediate network nodes. Using a CDN, improving origin performance, and choosing servers closer to users can reduce them.
