Uptime Checker FAQ & Guide
What is website uptime?
Website uptime is the percentage of time a website or web service is fully operational and accessible to visitors. 100% uptime means it never goes down.
How does this Uptime Checker work?
Our free tool sends an HTTP request directly to the target URL from our global monitoring servers, checking for a successful status code (like HTTP 200 OK) and measuring the time it takes for the server to reply.
Why do websites experience outages?
Common causes of downtime include server hardware failures, software bugs, domain registration expiry, expired SSL certificates, DNS configuration issues, database connectivity drops, or high traffic spikes (DDoS attacks).
What is a normal response time?
A response time under 200ms is considered excellent. Response times between 200ms and 500ms are normal. Anything above 1000ms (1 second) indicates latency issues that may hurt user experience and SEO rankings.
