Website Status Checker
Check website availability status from 6+ global locations instantly.
About Is It Down
Instant website availability checker that tests if a site is accessible from multiple global locations. Determine if the problem is you or the website.
Key Features
Multi-region availability check
Response time measurement
HTTP status codes
Redirect detection
SSL verification
Website status checking from multiple global locations helps you answer the critical question: is your site down for everyone, or just you? Instant verification from 6+ regions gives you confidence in your site's availability and helps identify regional outages.
Our multi-region website status checker tests HTTP/HTTPS connectivity, captures response codes, and measures response times from data centers across North America, Europe, and Asia-Pacific. This comprehensive view reveals issues that single-location checks would miss.
For complete website health monitoring, also verify your DNS configuration is correct and your SSL certificates are valid and not expiring soon.
**Methodology:** HTTP GET requests from 6 global probe locations with status code validation, SSL verification, and response time measurement.
Common Errors & How to Fix Them
4 relevant issuesThe server encountered an unexpected condition. This is a generic error when the server crashes or has a configuration problem.
1) For users: wait and retry—often temporary. 2) For site owners: check server error logs (tail -f /var/log/nginx/error.log), verify file permissions, check .htaccess for syntax errors, test PHP/application code locally.
The server acting as a gateway received an invalid response from the upstream server. Common with reverse proxies, load balancers, and CDNs.
1) For users: wait 5-10 minutes and retry. 2) For site owners: check if upstream service is running (systemctl status nginx php-fpm). 3) Verify proxy_pass configuration. 4) Check upstream server logs. 5) Increase proxy timeout values if requests are timing out.
The server is temporarily unable to handle the request due to maintenance or overload. Usually temporary.
1) For users: wait and retry—often means scheduled maintenance. 2) For site owners: check server resources (htop, free -m). 3) Scale up if overloaded. 4) Check if maintenance mode is accidentally enabled. 5) Review rate limiting settings.
The server didn't respond within the expected time. Could be server overload, network issues, or firewall blocking.
1) Check if server is reachable: ping example.com. 2) Test specific port: nc -vz example.com 443 -w 5. 3) Check from different location (VPN/proxy). 4) For owners: verify firewall allows traffic (ufw status), check server resources, ensure service is running.
Frequently Asked Questions
4 relevant questionsA website is considered "down" when it cannot be reached or fails to respond to requests. This can mean the server is offline, overloaded, misconfigured, or there's a network issue preventing access. Our tool checks from multiple global locations to determine if the site is down for everyone or just you.
When a website works for others but not you, common causes include: your ISP blocking the site, DNS cache issues on your device, local network problems, or geographic restrictions. Our multi-region checker tests from 6+ locations worldwide to definitively answer whether it's down globally or just for your location.
A site might be accessible in one region but down in another due to CDN issues, regional server failures, DNS propagation delays, or geographic blocking. Multi-region checking gives you the complete picture. If a site is down in only some regions, it often indicates CDN or load balancer problems rather than a complete outage.
200 means success—the site is up. 403 means access forbidden (you're blocked). 500 is an internal server error. 502 (Bad Gateway) means the server got an invalid response from an upstream server. 503 (Service Unavailable) means the server is temporarily overloaded or down for maintenance. 504 is a gateway timeout.
