Monitoring & Error Tracking
652 of the 1,000,000 top sites in our Tranco top-1M census run Pingdom (0.1%). A website uptime and performance monitoring service that alerts on downtime and slow load times. Detection is homepage-level HTML/header fingerprinting, so a site can run Pingdom on other pages without it showing here.
