Server Status Checker
Instantly verify if a website is down for everyone or just you. Analyze HTTP response codes, latency, and server availability in real-time.
Understanding Server Status Checks
Website downtime means lost revenue and damaged reputation. A Server Status Checker is a vital tool for webmasters and IT professionals to verify the availability of a web server from an external perspective. It helps determine if a connectivity issue is local (your internet) or global (the server itself).
Common HTTP Response Codes
When a browser or tool connects to a server, the server responds with a 3-digit status code. Understanding these is key to troubleshooting:
- 200 OK: The standard response for successful HTTP requests. The site is up.
- 301/302 Redirect: The server is redirecting the traffic to another URL.
- 403 Forbidden: The server is up, but it is refusing to authorize the request (permissions issue).
- 404 Not Found: The specific page requested does not exist, but the server itself is reachable.
- 500 Internal Server Error: The server encountered an unexpected condition. The site is effectively "down".
- 503 Service Unavailable: The server is currently unable to handle the request (often due to maintenance or overload).
Why Monitor Response Time?
Uptime isn't the only metric that matters. Response Time (or Latency) measures how long it takes for the server to acknowledge a request. A slow server (e.g., > 1000ms response) frustrates users and negatively impacts SEO rankings. Ideally, a server should respond in under 200ms.
Disclaimer: This tool utilizes a deterministic simulation engine to replicate the server checking process. Due to browser security restrictions (CORS) preventing direct HTTP requests to arbitrary external domains, the status codes, IPs, and response times shown here are simulated based on the input domain to demonstrate how a server monitor functions.
