Everything is up and working fabulous thanks to UptimeRobot.

A powerful uptime monitoring service with a wide range of domain and website monitoring features.

What I like most about UptimeRobot is the simple and quick setup combined with very reliable monitoring. The interface is clear, monitors are created in a few minutes, and notifications come reliably and without delay. It is particularly helpful that you can get a good overview of the availability of many services with little effort. For daily operations, the tool is stable, easy to understand, and focused precisely on the essentials.
