Is My Site Down?
Check if a website is accessible from multiple global locations. Find out if it's down for everyone or just you. Tests from our server plus 8 global DNS resolvers to detect regional outages.
How we check
Direct HTTP Check
We send an HTTP HEAD request from our server to the domain. If we get a response, we record the status code and response time.
Global DNS Resolution
We query 8 global DNS resolvers (Google, Cloudflare, Quad9, OpenDNS, etc.) to verify the domain resolves to an IP address everywhere.
Regional Detection
If some locations return results and others don't, you have a regional outage — the domain works in some parts of the world but not others.
Response Time
We measure how long each check takes. A response over 5 seconds is flagged as 'slow' — the domain is technically up but performing poorly.
DNS vs HTTP
We check both DNS resolution and HTTP connectivity. A domain can resolve in DNS but still be down at the HTTP level (server crashed, firewall blocking, etc.).
Just You or Everyone?
If we can reach the domain from multiple global locations but you can't, the issue is on your end — your ISP, network, or DNS cache.
If it's down — what to check
Down for everyone
Check your hosting provider's status page. Check if your server is running. Check if your SSL certificate is valid. Check if your domain registration has expired.
Down just for you
Flush your DNS cache (ipconfig /flushdns on Windows, sudo dscacheutil -flushcache on Mac). Try a different browser. Try a different network (mobile data). Check if your ISP is having issues.
Partially reachable
This usually means a CDN issue or DNS propagation problem. If you recently changed DNS records, some regions may still have the old records cached. Wait for TTL to expire.
Slow but accessible
The server is responding but taking too long. Check server resources (CPU, memory, disk). Check for traffic spikes. Consider using a CDN like Cloudflare.
