Uptime Check
Check whether a URL is up, with its status code and response time.
Check If a Website Is Up
Enter a URL and this tool requests it from our server and reports whether it is reachable, the HTTP status code it returns, and how long it took to respond. A status under 400 counts as up.
What it reports
- Up or down at a glance
- The exact HTTP status code
- Server response time in milliseconds
- Number of redirects before the final response
Up vs. down
A 2xx or 3xx response means the site is serving requests. A 4xx or 5xx, a timeout, or a connection failure means something is wrong — whether a missing page, a server error, or an outage.
Why check from a server?
Checking from our server gives a neutral, outside view of your site's availability — independent of your own network or browser cache. It is the same vantage point real visitors and search crawlers have.
One-time vs. monitoring
This is an on-demand check, not continuous monitoring. For production uptime alerts you'll want a dedicated monitoring service that polls on a schedule and notifies you, but a quick manual check is perfect for confirming a site is reachable right now.
