Does b-cdn.net block AI crawlers?
No. As of October 19, 2026, b-cdn.net's robots.txt allows all 17 AI crawlers we check everywhere. No group in the file applies to them.
Its /llms.txt is a text file that does not start with a Markdown title, so it does not follow the llms.txt format. The homepage is not an HTML page, so there was nothing to convert.
Each crawler, by its robots.txt rules
From https://bunny.net (15,244 bytes, 0 user-agent groups), parsed per RFC 9309. Blocked: no path allowed. Partly blocked: some paths disallowed. The rule counts are those of the groups that apply.
