Check if a website is online and measure its response time. Perform an HTTP Latency Test to verify server reachability and connection stability directly from your browser.
A ping test measures the time it takes for a data packet to travel from your device to a server and back. It is the primary way to test connectivity and latency (lag) on the internet.
Excellent connection. The server is likely close to your location or highly optimized. Great for fast loading speeds.
Slow response. Could be due to distance, server congestion, or network issues. Users might experience noticeable delays.
Essential for Webmasters.
Before blaming your ISP for a slow connection, ping the target website. If the latency is high or the request times out, the issue might be on the server side or a DNS propagation delay.
Isolate network issues.
This is often due to CORS (Cross-Origin Resource Sharing). For security, many major websites (like google.com) block browser scripts from fetching their content directly. The tool works best on your own sites or APIs that allow cross-origin requests.
Indirectly, yes. If the tool reports "Name Not Resolved" or immediate failure, it often indicates a DNS issue or that the domain does not exist.
