Website Diagnostics FAQ

Short answers for the technical questions people ask most often when a website does not load as expected.

What does MoniCheck check?

MoniCheck checks DNS resolution, HTTP response, SSL certificate validity, redirect handling and visible edge signals. The result is a readable technical snapshot, not just an online/offline label.

What does it mean if DNS resolution fails?

It means the domain did not resolve to a public address during the check. This may indicate missing DNS records, an expired domain or a configuration issue.

What does an HTTP status code tell me?

The HTTP status code shows how the server answered the request. A successful response is different from a 403, 500 or 503 result, and each points to a different next step.

Why can a website be reachable but still look restricted?

A firewall, CDN or access rule may answer the request while filtering it. In that case the site can still exist, but the response may not represent normal visitor access.

What does an invalid SSL certificate indicate?

It may indicate an expired certificate, a failed renewal or a TLS configuration problem. Site owners should review certificate installation and renewal before asking users to retry.

Does MoniCheck inspect redirects?

Yes. MoniCheck follows redirects during the check before reading the final response. Redirects can be normal, but broken rules may prevent access.

Can MoniCheck prove long-term uptime?

No. The result is point-in-time. It helps explain the current technical picture, but it is not continuous monitoring.

Why can my result differ from what I see in the browser?

Local DNS cache, browser state, regional routing or access rules can produce a different outcome. Compare from another network before assuming one result explains everything.

What should I check first if I own the site?

Start with DNS records, hosting status, recent deployments, SSL renewal and firewall or CDN rules. Those checks usually narrow the problem quickly.

What should I do if I am only visiting the site?

Retry later, compare from another network and avoid drawing strong conclusions from one failed request. The issue may be temporary or local.

Does MoniCheck evaluate page content?

No. MoniCheck focuses on availability and visible technical signals. It does not inspect every page, every script or every possible security condition.

How should I read unusual signals?

Treat them as reasons for caution and further checking, not as final proof. A technical signal can suggest where to look next without explaining every cause by itself.
