Is it down, or is it just you?
Stop checking by hand.
Add up to 10 sites for free. NoDisrupt checks them every 2 minutes and alerts you when one goes down.
If it is down for everyone
- 01Check the site's status page or social accounts: most services post incidents there first.
- 02If it is your site, start with what changed most recently: a deploy, a DNS edit, an expiring certificate or a renewed domain.
- 03A 5xx error means the server answered but failed, so look at the application and its database. No response at all points at DNS, the network, a firewall or the host itself.
If it is just you
- 01Try another network, such as mobile data instead of wifi. If it loads, the problem is your network.
- 02Open it in a private window, or another browser, to rule out cached files, cookies and extensions.
- 03Clear your DNS cache — macOS: sudo dscacheutil -flushcache; Windows: ipconfig /flushdns — then turn off any VPN, proxy or ad blocker and try again.
How this checker works
Each location makes a single HTTP GET request to the address you entered, follows redirects, and reports the final status code and how long the response took, or the error if there was no response. Requests come from the NoDisrupt API and from our check nodes, the same machines that run customers' uptime monitors. Private and internal addresses are refused, and each site can only be checked a limited number of times a minute, so the tool cannot be used to flood anyone.
Common questions
How do I check if a website is down for everyone or just me?
Enter the address above. The checker requests it from several locations at once, outside your network. If those locations load it and you cannot, the problem is between you and the site: your connection, DNS, browser or a block on your network. If they cannot load it either, the site is down.
What does each result mean?
Up means the site returned a 2xx or 3xx response, after following redirects. Responding means it answered with a 4xx error such as 403 or 404: the server is running but refused or could not find the page. Down means a 5xx error or no response at all, such as a DNS failure, a refused connection, a TLS error or a timeout.
Why does a site show 403 here when it works in my browser?
Many sites use bot protection that blocks automated requests from data centres while letting browsers through. A 403 from every location, alongside a page that loads for you, usually means exactly that rather than an outage.
Where are the checks run from?
From the NoDisrupt API in Stockholm and from every NoDisrupt check node that is online at the time, each listed by location in the results. Each location makes one HTTP GET request with a 10-second limit and follows up to a few redirects.
Can I share the result?
Yes. Every check gets its own link, which shows the same results for seven days. It is useful mid-incident, when someone asks whether it is just them.
How do I get told when my website goes down?
Use monitoring rather than checking by hand. NoDisrupt's free plan checks up to 10 sites every 2 minutes and emails you when one stops responding, with a public status page included.
