failover.io is an uptime monitoring service with cascading alert chains. It performs HTTP, cron/heartbeat, SSL certificate, and JSON-RPC checks, and escalates alerts across up to 10 channels until someone acknowledges. Each escalation step waits for an explicit acknowledgment before moving to the next channel, combining monitoring with incident escalation at flat-rate pricing.
