## Visiting the sites

If you visit one of our revoked sites, you might not get an error message. Revocation checking in browsers varies pretty widely, and has historically not worked great. Today's state-of-the-art is [Firefox's CRLite](https://hacks.mozilla.org/2025/08/crlite-fast-private-and-comprehensive-certificate-revocation-checking-in-firefox/), which is efficient and reliable. Ubuntu is deploying the same technology in their [upki](https://discourse.ubuntu.com/t/an-update-on-upki/77063) project. We hope other browsers and operating systems follow suit. The upki project is a great example of a project [making use of](https://github.com/rustls/upki/tree/main/revoke-test) these revoked test certificates, too.

The actual content of the website isn't terribly important: We just have a little HTML page explaining what the site is. But since this website is meant for testing clients, there's more than just browsers connecting. In particular, it's pretty routine that I try connecting with `curl` or some other terminal http client, and getting a bunch of HTML spewed to your terminal isn't very nice.
