Why Monitoring Website Status Matters
A website going down, even briefly, can mean lost visitors, lost revenue, and in some cases, a lasting hit to search rankings if outages are frequent or prolonged enough for search engines to notice reduced reliability. Knowing immediately whether a site is online, and how quickly it's responding, is a basic but essential part of maintaining any website's reliability.
How This Tool Works
Enter up to 100 URLs, one per line, and the tool checks each one, reporting back whether it's online or offline, its response time, and its HTTP status code — giving you a complete health check across many URLs simultaneously rather than checking each one individually by hand.
Common Use Cases
Website owners managing multiple domains or subdomains use this tool for routine health checks, quickly confirming everything is online and responding normally in one batch check rather than visiting each site manually. Agencies managing client websites use it to monitor a portfolio of sites efficiently, catching any outages before a client notices and reports it themselves. It's also useful after a hosting migration or server change, confirming that every page and subdomain came back online correctly rather than checking one at a time.
Tips for Best Results
Pay attention not just to whether a site is "online" or "offline," but also to its specific HTTP status code and response time — a site technically responding with a slow response time or an unexpected status code (like a 500 server error) may need attention even though it's not fully "down" in the most obvious sense.
Frequently Asked Questions
What does it mean if a URL shows as "offline" but I can access it fine in my browser?
This can happen due to firewall rules, geographic restrictions, or server configurations that block automated checking tools while still allowing normal browser traffic through — worth investigating if this happens consistently.
What's considered a "good" response time?
Generally, under one second is considered good for most websites, though this can vary depending on the type of content and expected user experience for your specific site and audience.
What do common HTTP status codes like 200, 404, and 500 mean?
200 indicates the page loaded successfully, 404 means the page wasn't found at that URL, and 500 indicates a server error — each pointing to a different type of issue worth investigating if it appears unexpectedly.
