The technical details
MarkdownHow to identify it
Look for the Google-GeminiNotebook identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.
How to check identity
Use Google’s published IP ranges for this crawler class and its forward-confirmed reverse DNS procedure.
Access and robots.txt
This user-triggered fetcher may ignore robots.txt. Use server access controls for private content.
Seeing 403 or 404 responses?
403 means access was denied; 404 means the resource was not found. Compare the public path, request time, edge security event and origin response to find the cause.
Separate intended restrictions and secret-file probes from pages that should work. A User-Agent name alone does not justify allowing a request.
