Uptime Checker
Know the second your site stops responding
We request your site over http, https, www and non-www, then report exactly which address answered, how long the server took, and what a visitor would see right now.
- All four addresses: http, https, www and non-www
- Whether HTTPS is working and trusted by browsers
- Server response time in milliseconds
- Whether the site answers on more than one address
