I've been thinking about returning a fake error page instead of the "you are banned" or "you country has been blocked".

Can you actually customize that Cloudflare error page? I thought that was their error page when they lose connection with your site and custom error pages was just the ones your app creates, like 404, 403, etc?

I think the intent is for joke pages, like the demo link which acts like error 500 saying the host is on fire etc but really serves as 200 OK, not your actual Cloudflare service errors.

You can, on the $30 plan - you can give it a hidden url on your current domain and it will cache & serve that content.

On free plans you can't, on business/enterprise plans you can.

Edit: Gemini says you could make a custom worker and do a 5XX redirect that way, but I haven't tried it. Does make sense though.

This works for errors at the origin or in a Worker, but won't for errors at the edge, because those are in front of Workers.

the custom error page is configurable at a domain (zone) level

which sometimes gets annoying because branding for subdomains could be different.

> Error Pages do not apply to responses with an HTTP status code of 500, 501, 503, or 505. These exceptions help avoid issues with specific API endpoints and other web applications. You can still customize responses for these status codes using Custom Error Rules.
