.DAY is a secure namespace: web browsers load .DAY websites only over HTTPS. To serve a website on a .DAY domain, you need an SSL certificate installed on your web server.

What do I agree to when I register a .DAY domain?

When you register a .DAY domain, the registration form asks you to confirm that you understand the HTTPS requirement. Check I acknowledge that HTTPS is required for all .DAY websites, as they will be encrypted by default and will not allow insecure connections. to continue.

How do I make a .DAY website work?

Browsers refuse plain HTTP connections to .DAY websites, so your web server must serve the site over HTTPS with a valid SSL certificate. You can get an SSL certificate through DNSimple. To learn more, read SSL Certificates at DNSimple.

A .DAY domain without an SSL certificate still works for email and other uses that do not go through a web browser.
