Frequently Asked Questions
What Traffic Patterns Should I Expect From Trellis-Services?
Trellis-Services's traffic often follows fixed intervals like a cron job. Activity may consist of short recurring checks or occasional intensive bursts, but it usually remains limited to a specific set of pages or endpoints.
Does Trellis-Services Follow Robots.txt Rules?
No. Trellis-Services is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Is Trellis-Services Used for AI Model Training?
Not ordinarily. Trellis-Services is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Trellis-Services Affect AI Search or Citations?
Not directly. Trellis-Services's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does Trellis-Services Access Private Content?
Only when configured with access. A team may grant Trellis-Services credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
How Can I Verify a Request From Trellis-Services?
Agent Analytics tracks Trellis-Services visits in real time. You can also check your server logs for requests whose user-agent string contains "Trellis-Services". Look for repeated checks of the same pages or endpoints at regular intervals. Because Trellis-Services does not publish a verification method, any client can claim its identity and a log match is only a clue.
