Why Is ELB-HealthChecker Visiting My Website?

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