Frequently Asked Questions
How does the server status checker work?
The tool sends an HTTP GET or HEAD request to the URL from our server infrastructure and reports back the HTTP status code (200 = OK, 4xx = client error, 5xx = server error) and response time in milliseconds.
What does it mean if a site shows as "up" but I can't access it?
The site may be accessible from our checking servers but down in your region (geographic outage), or your ISP/DNS may be blocking it. Try checking from different regions or clearing your DNS cache (ipconfig /flushdns).
What is a good server response time?
Under 200ms is excellent. 200–500ms is good. 500ms–2s is acceptable for complex pages. Over 2s indicates performance issues with server processing, database queries, or geographic distance.
Can I check non-HTTP services like game servers or email servers?
This tool checks HTTP/HTTPS endpoints. For TCP port checks (game servers, SMTP, database), use a port scanner or ping tool. For email server checks, use MX lookup to confirm DNS configuration.
Is there a way to set up automatic monitoring with alerts?
This tool is for manual one-off checks. For continuous monitoring with alerts, use dedicated uptime services like UptimeRobot (free tier available), Pingdom, or Better Uptime.
Is the 服务器状态检查器 free to use?
Yes, the 服务器状态检查器 on Allio Tools is completely free with no sign-up or registration required. It works directly in your browser.
How does the 服务器状态检查器 work?
实时检查网络服务器是否在线或离线。 Your input is processed on Cloudflare's edge infrastructure — it is not stored, logged, or shared with any third party.
Do I need to install anything to use the 服务器状态检查器?
No installation needed. The 服务器状态检查器 runs entirely in your web browser on any device — desktop, tablet, or mobile.
Is my data safe when using the 服务器状态检查器?
Yes. Your input is processed on Cloudflare's globally distributed edge network. Data is used only to generate your result and is never stored, logged, or shared with any third party.
Does the 服务器状态检查器 work offline?
No — the 服务器状态检查器 processes your input on Cloudflare's edge servers and requires an internet connection.
How current is the data returned by the 服务器状态检查器?
The 服务器状态检查器 fetches live data in real time each time you run it. Results reflect the current state of the server or domain at the moment of the request.
Why does the 服务器状态检查器 sometimes return different results than other tools?
Results depend on the real-time state of the target server and DNS propagation, which can vary by geographic region and caching TTL. If you see inconsistencies, wait a few minutes and re-test — DNS changes can take up to 48 hours to propagate fully worldwide.
Does the 服务器状态检查器 work on all browsers?
Yes. The 服务器状态检查器 is built with standard browser APIs and works on all modern browsers including Chrome, Firefox, Safari, and Edge — on both desktop and mobile. No plugins, extensions, or third-party software are required.
How do I save or export my results from the 服务器状态检查器?
Select and copy the result text to paste into any document or app. For image tools, a Download button saves the file directly to your device. Your browser's built-in screenshot function also captures results quickly. No account or login is required.
