Does netflix.net block AI crawlers?
netflix.net blocks 8 of 17 AI crawlers (Perplexity-User, CCBot, Bytespider, Meta-ExternalAgent, Amazonbot, cohere-ai, Diffbot and Timpibot), and allows 9 (checked 2026-10-01).
Retrieval crawlers are blocked too, so AI assistants that fetch a page live to quote and link it cannot read this site. Its content can still appear in answers from older training data or third-party copies, but not as a fresh, cited source.

How this was measured
We read netflix.net’s robots.txt, resolved it with an RFC 9309 matcher for each crawler’s product token, then fetched the homepage once as each crawler. A 403 or a challenge page is a block even when robots.txt allows the crawler; a timeout or rate limit is “not established”, never a block. One probe, from one location, on 2026-10-01, so a rule changed since then is not reflected here. Full methodology.
Check your own site
The free checker runs the same probe on any URL: robots.txt resolved for every AI crawler, then a live fetch as each one, so a CDN or firewall block shows up even when robots.txt looks fine.
