About Is It Down
Is It Down checks a website from outside your own connection and tells you in a few seconds whether it is down for everyone or just for you. That answers the first question when a site will not load: wait for them, or fix something on your side.
When a site is down you also see why it failed: the name does not resolve, the server does not answer in time, the secure connection fails, or the server returns an error code.
When it is up you get the status code, the response time and what to try on your side, from switching network to clearing the DNS cache.
Key Features
- Everyone or just you: a clear up or down verdict from outside your network.
- Failure reason: name not found, no answer in 10 seconds, secure connection failed or a server error with its code.
- Status code and response time: the exact answer the server gave and how long it took.
- Redirects shown: when a site sends you elsewhere, the final address is listed.
- Recent checks: the sites you checked stay listed in this browser, so a recheck is one click.
- Any address works: paste a full link or type a bare domain; it is cleaned up for you.
How to Use
- Enter the site: type a domain such as example.com or paste a link.
- Press Check: the result appears in a few seconds.
- Read the verdict: green means the site answered, red means it is failing for everyone.
- Follow the advice: if it is up but will not open for you, try the steps shown under the result.
- Check again later: use the recent checks list to retest an outage.
Common Use Cases
- A site will not load: find out in seconds whether to wait or to troubleshoot your own connection.
- Your own website: confirm an outage reported by a visitor before you start digging.
- Games, chat and AI apps: check whether the service itself is down before reinstalling anything.
- After a DNS change: see whether the new address is answering yet.
- Support conversations: give a provider the exact error and status code instead of "it does not work".
Frequently Asked Questions
What does "down for everyone" mean?
The site failed when checked from outside your network as well, so the problem is with the site or its hosting, not with your device or connection.
The site is up here but will not open for me. Why?
Common causes are a cached old address in your device, a VPN or ad blocker, a network filter at work or school, or a problem with your provider. Try mobile data to narrow it down.
Why does a site show up even though it shows an error page?
A page that asks you to log in, blocks bots or says "forbidden" still means the server is answering. Only server errors, timeouts and unreachable servers count as down.
How often is a site checked?
A site checked in the last minute shows that result again, so many people asking at once get a fast answer. Check again a minute later for a fresh result.
Can I check a site with a port or an IP address?
No. Only public websites by name on the standard web ports can be checked.
What do the status codes mean?
Codes from 200 to 399 mean the site answered normally or redirected. 400 to 499 mean it answered but refused the request. 500 and above mean the server failed.
Pro Tips
- Test on mobile data: if the site opens there, the problem is your home network or provider.
- Clear the DNS cache: after a site moves to a new server, an old cached address can keep it unreachable for you.
- Turn off extensions: privacy and ad blocking extensions sometimes block a whole site.
- Watch the response time: a site that answers in several seconds is overloaded and may go down next.
- Check the exact page: a site can be up while one part, such as a login or an app domain, is down; check that domain directly.
