Is it down, or is it just you?

Type any website. We check it live from our server and tell you if it is up, how fast it answered, and if not, why.

SentryWatches your site
  1. Looking up the domain
  2. Connecting to the server
  3. Loading the page

What the result means

Up means our server reached the website and got a normal page back. Down means something failed on the way, and we tell you which part: the domain name, the connection, the security certificate, or the server itself.

What you seeWhat it usually means
Domain not foundThe domain has expired or its DNS settings were changed.
Timed outThe server is overloaded, switched off or blocking visitors.
Certificate failedThe padlock certificate has expired or was set up wrongly.
Error 500 to 599The server answered but the site crashed, often after an update.
Error 404 or 403The server works, but that page is missing or access is refused.

If it is up for us but not for you

Your browser may be holding an old copy, your network may be blocking the site, or your internet provider's DNS may be slow to catch up after a change. Try another browser, switch off any VPN, or test on mobile data.

Questions

Is the website down for everyone or just me?

If our check says the site is up, the problem is probably your connection, browser or network. Try another browser, mobile data or clearing your cache. If our check says it is down, it is down for everyone.

Where do you check from?

From our own web server, not from your device. A site can occasionally block some countries or networks, so your result might differ from ours.

What is a security certificate expiry?

The certificate behind the padlock has an end date. If it runs out, every visitor sees a full-page warning. Most hosts renew it automatically, but it is worth knowing the date.

My site is down. What should I do?

Check your hosting account for an outage notice, check your domain has not expired, and contact your host. If the error is 500 or above, something on the server broke, often after an update.
