How to check if a website is down (for everyone or just you)
When a site won't load, the first question is simple: is it down for everyone, or just for you? The answer points straight at the fix.
What it is
“Down” can mean several things: DNS doesn't resolve, the TCP/TLS connection fails, or the server returns an error status (5xx). Each points to a different cause — and a check from outside your own network tells you which.
Why it matters
Knowing where it breaks saves hours. A DNS failure is a registrar/DNS issue; a TLS failure is a certificate problem; a 5xx is the application; a timeout is the network or server load. Guessing wastes time during an outage.
How to check
Enter the URL in the tool above. It checks DNS, the TCP/TLS handshake and the HTTP status from outside, reports response time, and gives a plain verdict on whether the site is reachable and healthy.
How to fix
- Only you? Flush DNS, try another network or device, disable VPN.
- DNS fails? Check your records and registrar.
- TLS fails? Renew/repair the certificate.
- 5xx? Check application logs and server resources.
- Set up uptime monitoring so you're alerted before customers complain.
