Check whether a site is down for everyone or just you — we test it live from the cloud.
We send a live HTTP request to your URL from our monitoring infrastructure and report the status code and response time. If we can reach the site, it's up for the wider internet — and the problem is likely your local network, DNS cache, or ISP. If we can't, the site is genuinely down.
Common causes of downtime: expired SSL certificates, expired domains, server crashes, misconfigured DNS, and hosting provider outages. Continuous monitoring catches these within minutes instead of hearing about it from your customers.
This free downtime checker tests any URL from our cloud servers, so you can see whether a site is down for everyone or just you. Use it as a quick down detector after a deploy, a DNS change, or a hosting migration — and if you want a continuous downtime tracker instead of manual checks, PingDeck monitors your site 24/7 free and alerts you the moment it stops responding.
