Pingdom is a commercial monitoring service that periodically checks the availability and response speed of websites and servers from the outside. It checks HTTP, DNS, TCP ports, and more from multiple locations around the world and sends alerts by email, SMS, or messenger when an outage occurs. It also provides uptime reports, page load time analysis, and transaction checks that replay user flows. It was acquired by SolarWinds; similar services include Checkly and UptimeRobot.
