Live Status Checks
Is It Down?
Find out whether a website is down for everyone or just for you. Checks are verified from Sentinel's monitoring network across multiple regions, not one location. No signup needed.
How it works
Checked from fifteen regions, not one.
Type the site
Enter a domain like example.com. No account, no signup.
Fifteen regions check it
Probes in fifteen regions on six continents request the site at the same moment.

Is it down for everyone or just me?
Type the domain above and you will know in a few seconds. If every region reaches the site, it is up and the problem is on your side: a stale DNS cache, a VPN, a firewall, or your ISP. If no region can reach it, it is down for everyone.
Which websites are down right now?
Each popular site below has its own live page showing the latest check from all fifteen regions, so you can see at a glance whether a major service is having trouble. Any other domain can be checked by typing it above.
How does this check work?
When you look up a site, we verify it from Sentinel's monitoring network, not from a single computer. Requests go out from multiple regions around the world, so a routing problem or outage in one part of the internet does not produce a false answer. If the site responds to our checkers, it is up; if none of our regions can reach it, it is down for everyone.
Why can a site be down only for me?
Plenty of failures are local: your DNS cache holding a stale record, your ISP having a routing issue, a VPN or firewall blocking the site, or your browser cache serving a broken page. If our network can reach the site but you cannot, try another network or device, flush your DNS cache, or disable your VPN before assuming the site itself is broken.
How do I find out the moment my own site goes down?
Checking by hand only works if you happen to be looking. Sentinel monitors your site around the clock from multiple regions and alerts you within moments of an outage, before your visitors start emailing you about it. The free plan includes uptime monitoring with no credit card required.
Know before your visitors do.
Sentinel watches your site around the clock from multiple regions and alerts you the moment it goes down, so you are never the last to find out.
