As of the last check, example.com is UP and responding normally. The server returned HTTP 200. Response time was 43ms. Use the re-check button for real-time status.
There are several reasons a site may be unreachable: the server could be overloaded, undergoing maintenance, or experiencing an outage. Your ISP might be blocking the domain, or DNS propagation could be in progress after a recent change. This tool checks from our servers — if the site shows UP here but not for you, the issue is likely local.
HTTP 200 means OK — the page loaded successfully. 301/302 are redirects. 403 means forbidden. 404 means not found. 500-level errors indicate server-side problems. 503 usually means the service is temporarily unavailable, often during maintenance or an outage.
DNS down means the domain name does not resolve to an IP address — requests never reach the server. Site down means DNS resolved correctly but the server is not responding or returning errors. This tool checks both separately so you can diagnose the exact failure point.
For production websites, monitoring every 1–5 minutes is recommended. This tool provides on-demand checks. For automated continuous monitoring, consider services like UptimeRobot (free), BetterUptime, or Pingdom. Average uptime for well-maintained sites should exceed 99.9%.
