Website down checker
Find out whether a site is down for everyone or just for you. Free, no signup.
Know before your customers do
A one-off check answers the question you already have. WWT checks every minute and tells you the moment a site stops answering, along with its certificate, domain and email records.
How to read the result
The probe runs from our servers, not from your browser, which is exactly what makes the answer useful: it tells you whether the outage is yours or everyone's. A successful response means the site is serving traffic and any problem you are seeing is local to your network, your DNS resolver or your browser cache.
When the site is genuinely down, the status code narrows down where to look. No response at all points at the server or the firewall; a name that does not resolve points at DNS or an expired domain; a 5xx means the server is alive but the application is failing; a 502 or 504 means a proxy cannot reach the application behind it.
About website availability
Why check from outside my own network?
Because most of what people call an outage is not one. A cached DNS entry, a VPN, a corporate proxy or a stale service worker will break a site for you alone. A probe from somewhere else separates those cases in one step.
The check says up, but the site does not load for me. Why?
Something on your path is failing. Try the same address from a phone on mobile data: that bypasses your DNS resolver, your router, your network and your browser cache at once, and usually settles it immediately.
What counts as up?
Any HTTP status from 200 to 399. That covers normal pages and redirects. A 4xx or 5xx means the server is reachable but not serving the page, which we report separately because the fix is completely different.
Why does it say HTTPS is missing?
We try HTTPS first and fall back to plain HTTP. If only HTTP answered, the site is technically up but has no working TLS, and browsers will mark it as not secure. That is usually a certificate or web server configuration problem rather than an outage.
How is this different from monitoring?
This checks once, right now, because you asked. Monitoring checks every minute without being asked and alerts you when the answer changes, which is the only way to catch an outage that starts at three in the morning.
