What this measures
This sends a single request to the URL you provide and times how long the server takes to respond, along with the HTTP status code returned. It's a quick spot-check — useful for confirming a site is currently up, or getting a rough sense of server responsiveness — not a substitute for continuous monitoring.
Frequently asked questions
Why might this show a different response time than my own browser?
This runs from a server in a different network location, so latency naturally differs based on network distance, routing, and any CDN the target site uses.
Is a single check enough to know if a site has reliable uptime?
No — it only confirms status at that moment. Real uptime monitoring needs repeated checks over time from a dedicated service that can alert on outages and track historical availability.
What response time is considered good?
Under 200ms is generally fast for a server response (excluding full page load, which includes other assets). Above 1 second often signals a server-side issue worth investigating.
