Is the host even reachable?
Know in milliseconds.
Send ICMP (with TCP fallback) to verify host liveliness and network reachability. Track round-trip latency and packet loss, and probe from multiple regions to isolate where the network breaks.

Beyond just "is it up?"
Knowing a host is reachable is only the start. Track latency trends, catch packet loss before it becomes an outage, and probe from multiple regions to pinpoint exactly where the network is failing.
Reachability checks
ICMP echo requests with automatic TCP fallback mean hosts behind restrictive firewalls are still covered. Confirm a machine is up at the network level before anything else can go wrong.
- ICMP echo with automatic TCP fallback
- Alert on sustained unreachability
- Sub-second precision
Latency & packet loss
Round-trip time that creeps up is an early warning sign. Track RTT over time and catch intermittent packet loss before it manifests as timeouts, retries, or application errors for your users.
- Track round-trip latency over time
- Detect intermittent packet loss
- Set latency and loss thresholds
Round-Trip Latency
Multi-region probing
A host that's unreachable from Asia but fine from Europe points to a routing issue, not a server crash. Probe simultaneously from multiple regions to isolate exactly where the network breaks.
- Probe from multiple regions simultaneously
- Pinpoint regional connectivity issues
- Compare per-region latency
