Guides
What Check Server Status does
Paste a list of URLs and this tool checks each one server-side — is it reachable right now, what HTTP status did it return, and how long did it take to respond. Useful for a quick uptime spot-check across a set of sites, or to confirm a batch of links still resolve after a migration.
How to use it
- Paste up to 20 URLs, one per line.
- Click Check status. Every URL is checked in parallel server-side (cross-origin requests can't be read in the browser).
- Review the Summary for how many came back online, and the Per-URL results table for each one's state, HTTP status code, and response time.
Online vs. offline
A URL counts as online if it returns any HTTP status under 400 (including redirects, which are followed automatically). Anything that returns a 4xx/5xx status, times out, or fails to connect at all counts as offline — the same distinction whether the site is actually down or just returning an error page.
What this doesn't do
This is a single reachability check from our server, not a multi-region monitoring service — it won't tell you if a site is down for everyone or just from one location, and it doesn't run on a schedule. For a closer look at a single URL's redirect chain, see the Redirect Checker.
Privacy
URLs are fetched by our server only to check their status and aren't stored. Requests to private or local network addresses are blocked.
