Is It Down?

What is Website Monitoring?

Website monitoring periodically checks whether a website is reachable and responding correctly. Our tool checks from Frankfurt, Germany so results reflect real-world availability from a central European server, not just your local network. Each check sends an HTTP HEAD request (falling back to GET if needed). HTTP 200–399 within 10 seconds = UP; anything else = DOWN. Results build a rolling history of the last 20 checks per domain.

Is It Down for Everyone, or Just Me?

If our checker shows UP but you cannot access the site, the problem is on your end. Common fixes:

• Flush DNS cache ipconfig /flushdns (Windows) · sudo dscacheutil -flushcache (macOS) · sudo systemd-resolve --flush-caches (Linux)
• Hard reload browser Ctrl+Shift+R or open incognito
• Try a different network switch to mobile data or a VPN to rule out ISP-level blocks
• Check firewall / antivirus temporarily disable and retry

Why Is a Website Down?

Common causes of outages: server overload, DDoS attacks, scheduled maintenance, database failures, DNS propagation issues after domain changes, expired SSL certificates, or data centre / hosting provider outages. Click any site in the table above for a full status history and response-time graph.

How to Use This Tool

Type any domain into the search box bare domain (example.com), full URL (https://example.com), or subdomain (mail.google.com). After submitting you'll see: current UP/DOWN status, HTTP code, response time in ms, uptime % over 20 checks, a response-time bar chart (green = UP, red = DOWN), last downtime timestamp, and a live auto-refresh every 60 seconds. For popular sites you'll also find a link to community outage reports on DownDetector.
