The HTTP status code (e.g., 200, 404, 500) tells you the server's response. 200 means OK, while 5xx errors indicate server-side problems.

Is this status result real-time or cached?

This check is performed in real-time. We ping the server at the exact moment you load this page to ensure the most accurate status.

Can this tool detect ISP or regional outages?

Yes, we use a distributed monitoring network. If a site is down in one region but up in others, our global nodes section will highlight the discrepancy.

Does this checker verify SSL certificates and expiration?

Yes, we inspect the SSL certificate chain for validity, expiration date, and issuer trust. Expired certificates will trigger a warning even if the site loads.

How often is this website checked?

We perform automated checks every 5-10 minutes for popular sites. For less frequent sites, checks are triggered on-demand when a user visits the status page.

Is this issue global or only affecting me?

If our status says UP but you can't access it, the issue is likely local (your ISP, DNS, or browser cache). If we say DOWN, it is a confirmed global outage.
