Check whether any website is down or just unreachable from your connection — a fast browser-based probe with honest, plain-English results. This free is it down checker needs no signup and runs entirely in your browser.
What is the Is It Down Checker?
An is it down checker answers one of the internet’s oldest questions: is this website actually down, or is the problem on my end? Paste any URL and your browser probes the site directly, reporting whether it could connect.
This free tool works by sending a lightweight request from your browser to the address you enter. If the connection succeeds, the site is reachable — the problem is likely your connection, VPN, ad blocker or DNS. If it fails, the site may genuinely be down, but there’s an honest caveat built into the page: browsers enforce security rules (called CORS) that prevent reading the full response from other websites, so a failed probe can be a false negative when a site simply blocks cross-origin requests.
It runs entirely in your browser with no signup, and the result is paired with plain-English guidance on what to do next: retry the site directly, test on another network, or check a status page. Use it as a fast first triage step — ‘is it me or is it them?’ — rather than a definitive uptime monitor.
How to use the Is It Down Checker
- Type or paste the website address — with or without https:// — into the field.
- Press Check Status. Your browser sends a lightweight probe request to the site.
- Read the result: ‘reachable’ means your browser successfully connected; ‘unreachable’ means it couldn’t.
- If the result is unreachable, open the site in a new tab to double-check, since browser security limits can cause false negatives.
- Use the built-in link to retry the site directly or search for outage reports.
Is It Down Checker use cases
‘Is it me or is it them?’
When a site won’t load, this answers the first question in seconds: is it the site, or is it my connection? That decides whether you wait, reboot your router, or contact support.
Admins verifying a deployment
Admins run a quick probe after deploying changes or restarting a server to confirm the site answers from a normal browser before declaring victory.
Shoppers during checkout failures
Shoppers and account holders check whether a checkout or login failure is a site-wide outage before retrying payment or resetting passwords.
Remote workers and IT triage
Remote workers verify whether a company portal or SaaS dashboard is down for everyone before escalating to IT.
Tips
- A single failed check doesn’t prove a site is down — your own connection, a VPN, or a firewall could be the cause.
- Check on a different network (mobile data vs Wi-Fi) to tell whether the problem is the site or your connection.
- ‘Reachable’ from your browser means the server answered your network request — the site’s pages could still be broken.
- For famous outages, searching the site name plus ‘down’ finds status pages and real-time reports faster than any probe.
