Why Is DowntimeDetector Visiting My Website?
Someone, most likely on your own team, configured DowntimeDetector to check your site. Uptime monitors, performance testers, and audit tools visit only the sites or endpoints they are told to watch.
Should I Block DowntimeDetector?
Only if no one on your team relies on it. DowntimeDetector may support uptime monitoring, performance tests, or audits. Blocking it without checking first can silently disrupt those workflows. For context, 7% of the top websites we track currently have robots.txt rules for DowntimeDetector.

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