Gaps
- high12 of 14 AI agents are blockedAssistants asked about this page will guess, or cite someone else. Deliberate for a paywalled publisher. Otherwise this is the biggest gap on the list.
- mediumBot-management challenge served to crawlersGooglebot, GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, Claude-SearchBot, Claude-User, PerplexityBot, Perplexity-User, Bingbot, Meta-ExternalAgent, Amazonbot, Bytespider, CCBot received an interstitial instead of the page. A robots.txt rule is an honest block. A challenge hides the page without saying so.
- highGooglebot is blockedBot challenge served (HTTP 403)
- infoGoogle-Extended not listedYou block other training crawlers but Gemini training via Google-Extended is still allowed. Add it to the same group if the policy is meant to be even-handed.
- infoCanonical points elsewhereCanonical is https://www.cisco.com/. Indexes will credit that URL, not this one.
