Features
Everything you need to run reliable services.
Monitoring, alerting, incident management, status pages, and reliability reports — a complete monitoring platform, not just uptime checks.
Monitoring
Watch every layer of your stack, from HTTP down to TCP, from multiple geographic locations.
Multi-location checks
Every check runs from multiple geographic locations, separating regional issues from global outages.
Ping & TCP
Reachability, packet loss, and port checks at the network layer.
DNS
Resolution health and expected-record validation.
TLS / SSL
Certificate validity, issuer, and expiry countdown.
Domain expiry
Track registration expiry before a domain lapses.

Latency thresholds that raise a performance incident.

Reach the right people on the right channel, every time.
Every channel
