Is my website down right now?
Type your address and we send one real request from our network. You get the answer, the HTTP status, the response time, and what to do about it.
How this check works
When you press the button, a server in Oh Snap's network sends one normal web request to your address, the same kind a browser sends, and waits up to 10 seconds. We follow up to three redirects, so www and http-to-https hops are handled.
We report exactly what came back: the HTTP status code and how long it took. A 2xx means up. A 5xx or no answer at all means down. A 404 means the server is fine and the page isn't, which is a different problem with a different fix.
Some sites sit behind firewalls that block automated visitors with a 403 or a challenge page. We recognise those and call the site up, because real people get through. Results are kept for one minute so a burst of checks doesn't hammer your server.
Common questions
How do I know if my site is down for everyone or just for me?
Use a checker like this one, or open the site on your phone with Wi-Fi off. If it loads from somewhere else, the problem is your browser, your network, or your DNS cache, not the site. Try a hard refresh (Ctrl or Cmd + Shift + R) and a private window.
Why does the check say up when I can't open the site?
Because the answer came back from our network, not yours. Your browser may be caching an old error, your office network may be blocking the domain, or your DNS may be stale after a change. Wait a few minutes, clear the cache, or try another network.
What does "the server is up but the page isn't" mean?
The server answered, but with a client error such as 404. Visitors reach your host fine; the specific address is missing, moved, or blocked. Check the exact URL, recent content changes, and any redirect rules.
What do errors 500, 502, 503 and 504 mean?
They are all server-side failures. 500 is a generic application crash, 502 and 504 mean a gateway couldn't reach the application behind it, and 503 means the server is overloaded or in maintenance. Start with your host's status page and your most recent deploy.
Where is the check made from?
From one location in Oh Snap's network, close to wherever you are. That's enough to answer "is it up right now". Continuous monitoring is different: OhSnap checks on a schedule and confirms a failure before alerting, so a single hiccup doesn't wake you up.
How do I get alerted the next time it goes down?
Add the site to OhSnap. The free plan watches 5 sites, checks every 5 minutes, and sends email and SMS alerts. The paid plan adds 30-second checks and WhatsApp.
Don't find out from a customer.
OhSnap tells you the moment your site goes down, and again when it recovers. Free for 5 sites, alerts included.
