How this check works

Live, on-demandEach check is a fresh request made right now - this is not a background monitor that runs continuously.

Single vantage pointThe check runs from this server, not from multiple global locations, so results reflect this one connection path.

Warning vs down"Warning" means the site responded but slowly or with an SSL issue; "down" means it didn't respond successfully at all.

Private historyRecent checks are saved only in your browser's local storage - they are not sent anywhere or shared with anyone.

About Website Uptime Checker

Website Uptime Checker performs a live check of any website right from your browser and reports back whether it is up, down, or responding slowly. Enter a URL and the tool makes a real-time server-side request to it, then reports the HTTP status code, response time, resolved IP address, redirect chain, server header, and - for HTTPS sites - SSL certificate validity and days until expiry. Each check is a fresh, on-demand snapshot rather than a running background monitor, so it tells you the site's status at the moment you check it. Your last several checks for each URL are kept locally in your own browser so you can compare response times over your recent checks at a glance.
