How it works

  1. 1
    HTTPS handshake

    Your browser performs DNS, TCP, and TLS against the host — exactly like a real visitor.

  2. 2
    Response timed

    We measure milliseconds from request to first byte.

  3. 3
    Failure mode reported

    Unreachable hosts get a clear explanation: DNS, blocking, or no route.

Real use cases

  • — Triage an outage: is the server down or just slow?
  • — Validate a deploy reached the load balancer.
  • — Confirm a firewall change didn't black-hole your service.
  • — Set a baseline before scheduled maintenance.
