Frequently Asked Questions
Common questions about the website and domain status checker. For a deeper guide on interpreting results and HTTP status codes, see our Guide.
How does the checker work?
When you submit a URL, we normalize it, validate the domain, check DNS resolution, then attempt an HTTP(S) request and report the HTTP status code, timing, redirects, and basic page metadata when available.
Is this an uptime monitor?
No. This tool is designed for quick, on-demand checks. For monitoring uptime over time, use a dedicated uptime monitoring service.
Why do some websites show "Online but Limited"?
Some sites block automated requests (rate limiting, bot protection, or Cloudflare challenges). In that case we can often confirm the site is reachable, but may not be able to fetch full page content.
What URLs are not allowed?
For security reasons, we block checks to local/private networks (e.g. localhost, 127.0.0.1, 192.168.x.x) to prevent abuse.
Do you store the URLs I check?
We do not intentionally store the URLs you submit in a database. Standard server logs may record basic request information (as most web servers do). See our Privacy Policy for details.
What do the results mean?
Online means the site responded successfully (usually HTTP 200). Offline or Error means the request failed (e.g. DNS issue, connection refused, or timeout). Online but Limited means we could reach the server but some content or metadata was blocked (e.g. by bot protection). The HTTP status code (200, 404, 500, etc.) and response time give more detail for troubleshooting.
What is an HTTP status code?
An HTTP status code is a number the server returns with every response. Common ones: 200 (OK), 301/302 (redirect), 404 (Not Found), 500 (Server Error). The checker shows this code so you can see exactly how the server responded. See our Guide for a full explanation of common codes.
Can I check multiple URLs?
You can run one check at a time. Enter a URL, get the result, then enter another. We do not support batch checking or automated API access. For ongoing monitoring of many URLs, use a dedicated uptime monitoring service.
