Is my site down,or is it just me?
Type the address. We fetch it from our server, outside your office and your browser cache, and tell you whether it is up, what it answered and, if it is down, why and what to do in the next five minutes.
One moment.
Why sites go down
Almost never a mystery. It is usually the last thing that changed, and the tool names which of these it is looking at.
- 01
The domain expired
Renewal notices go to an old inbox, the name lapses, and the site becomes a parking page overnight.
- 02
The host suspended the account
An unpaid invoice, a malware report or a resource limit. The site is replaced by the host's notice.
- 03
An update went wrong
WordPress, a plugin or PHP was updated and something did not survive it. White screens and maintenance notices start here.
- 04
The certificate lapsed
The site is fine; the padlock is not. Browsers put a warning page in front of it and most visitors turn back.
- 05
DNS was changed
A new host, a new email provider or a well-meaning edit sent the domain somewhere that is not the site.
- 06
The server is overloaded
A traffic spike, a bot or a runaway process. The site answers slowly, then not at all.
Before you call anyone
- 1Run the check above. If we can reach the site, start with your own connection: a private window, your phone off Wi-Fi.
- 2Write down the exact error and the time. Screenshots help whoever fixes it.
- 3Think about what changed today. An update, an invoice, a DNS edit, a new plugin. That is the suspect.
- 4Do not restore a backup or reinstall anything yet. Half of the sites we rescue were made worse in the first hour.
Site down and you need it back up?
Tell us what the check found and how to reach you. Outages go to the top of the pile, and you get a plain answer before anyone touches the site.
Which of these sounds like you? (pick any)
Frequently asked
Check it from somewhere that is not your computer or your network. That is what this tool does: it asks our server to fetch your site and reports what it saw. If we reach it and you cannot, the problem is on your side, usually a cache, a DNS setting or a security product.
From our servers in the United States. A site can be reachable from one place and blocked from another, so a clean result here does not rule out a problem for visitors elsewhere, but it does rule out the site itself being down.
The most common reasons are a certificate warning they are clicking away from, a slow server that times out on their connection or a page that loads but shows an error inside it. Run the full health check next; it looks at the certificate and response time in detail.
Do not change anything yet. Note the time, read the error the tool reports, and check whether anything about the site changed today: an update, a bill, a DNS edit, a new plugin. Nine times in ten the cause is the last thing that changed.
No. It tells you what is wrong and points you to the guide for that exact failure. If you would rather hand it to someone, the form on this page reaches us directly and site-down requests go to the top of the pile.
So the tool cannot be pointed at someone else's server by a script, and so we know who to help if the site really is down. One six-digit code, once, and every tool on the site is open for thirty days on that browser.
Because it fetches other people's servers on request, and a tool like that gets abused. Each visitor gets a generous number of checks every ten minutes and each site can only be checked so often. If you hit the limit, wait a few minutes.
