Know whether the host answers the probe.
Is the host reachable? Ask from more than one place.
Use regional ICMP checks to track reachability and round-trip latency, then record the path from failure to recovery.

See how long a successful response takes.
Compare observations from more than one place.
A small packet can answer a very useful first question.
Check whether a host responds from the regions you choose and keep the observed latency beside every state change.
Reachability
Watch the host without pretending ping is everything.
Use ICMP as a fast, focused availability signal for hosts that should respond. Keep application behavior with HTTP and API monitors.
- Track reachable and unreachable state changes.
- Configure the check cadence available to your plan.
- Keep the target and observed result attached.
Incidents
Coordinate updates from first signal to recovery.
Fair questions. Straight answers.
It checks ICMP reachability and records round-trip latency for successful responses from the configured locations.
Ask whether the host answers. Keep the regional evidence.
Add a focused reachability signal to the rest of your monitoring context.
