HTTP Health Probe

HTTP Health Probe is a networking availability check that tests whether a service or path can receive traffic for application-layer request routing. It uses timed requests, thresholds, and regional checks so teams can send traffic only to healthy targets while keeping evidence, reliability, and public-safe operational boundaries clear.

“The network engineering team used HTTP Health Probe when a client retried a request, so the team could send traffic only to healthy targets before traffic crossed a service boundary.”
