Is this website down? Check from 24 locations.

Enter any URL and Emercom checks it from 24 servers across 13 countries at once — HTTP status, response time, SSL and headers per location — so you can instantly tell whether an outage is regional or global. Free, no signup.

Check response status, timing, and availability of any URL from 24 servers worldwide. Paste any HTTP/HTTPS URL — full path, query string, anything reachable from the public internet.

What is an HTTP Check?

An HTTP check is a network request sent to a web server to verify that a URL is reachable, responding correctly, and returning the expected content. When you run an HTTP check, the monitoring agent connects to your target URL, records the HTTP status code, measures the total response time, inspects SSL certificate validity, and follows any redirect chains — giving you a complete picture of how your website behaves from the outside.

Unlike a simple ping, which only confirms that a server is reachable at the network level, an HTTP check validates that the entire web stack is functioning: DNS resolution, TCP connection, TLS handshake, application response, and content delivery. A server can be "up" at the network layer while returning HTTP 503 errors or serving corrupted pages — an HTTP check catches these issues that a ping would miss entirely.

Emercom runs HTTP checks from 24 monitoring servers simultaneously, spanning 13 countries across 5 continents. This shows you where your site is up — which matters when serving a global audience through CDNs, load balancers, or multi-region infrastructure.

A ping says "the server is alive". An HTTP check says "the website is actually working" — DNS resolved, TLS handshake succeeded, application replied, content delivered. Five layers, one verdict.

Understanding HTTP Status Codes

Every HTTP response includes a three-digit status code that tells you what happened with your request. Codes are grouped by their first digit: 2xx means success, 3xx redirection, 4xx a client-side problem, and 5xx a server-side problem. Knowing what each code means helps you diagnose website issues quickly and accurately.

Code Name Meaning
200 OK The request succeeded. The server returned the requested resource.
301 Moved Permanently The resource has permanently moved to a new URL. Browsers and search engines update their records.
302 Found Temporary redirect. The resource is temporarily at a different URL; the original URL should be used in future requests.
403 Forbidden Access denied. The server understood the request but refuses to authorize it — often due to IP blocking, firewall rules, or missing permissions.
404 Not Found The resource does not exist at this URL. The page may have been deleted or the URL may be incorrect.
500 Internal Server Error A generic server-side error. The server encountered an unexpected condition that prevented it from fulfilling the request.
502 Bad Gateway The server received an invalid response from an upstream server. Common when a reverse proxy (nginx, Caddy) cannot reach the backend application.
503 Service Unavailable The server is temporarily unable to handle the request — usually due to overload, maintenance mode, or a crashed application process.

Why Check From Multiple Locations?

A website can appear fully operational from one location while being completely unreachable from another. This happens more often than most website owners realize, and single-location checks will miss these regional failures entirely. Here are the four most common causes:

  • CDN edge node failures. A misconfigured or down edge in one region leaves users there hitting errors while everyone else is unaffected.
  • DNS propagation lag. After a zone change, some resolvers around the world cache old records for hours — your new server is reachable from some places but not others.
  • BGP routing & ISP outages. Route announcement errors or ISP-level peering issues can black-hole traffic from entire regions while neighbouring networks see no problem.
  • Geo-blocking misconfigurations. Firewall or DDoS rules implemented incorrectly may block legitimate traffic from specific countries — a problem invisible to anyone outside that country.

By running HTTP checks from all 24 Emercom locations simultaneously, you immediately see which regions are experiencing problems and which are not. A result that comes back up from most locations but down from two or three of them points directly at a regional issue — whether that is a CDN edge failure in Asia-Pacific, a DNS lag in Europe, or a geo-firewall misconfiguration blocking specific IP ranges. This kind of insight is impossible to get from a single-location check.
