In plain words
Everyone Panic combines Uptime Robot, Google App Engine, and Twilio to deliver phone call alerts when websites go down. The service automatically detects outages and immediately calls designated numbers, ensuring urgent notifications aren't missed during off-hours when email and text alerts might go unnoticed. Built by DoubleMap Engineering for their GPS bus-tracking system, it uses a Python application to integrate monitoring and calling services at minimal cost, making it suitable for teams requiring immediate downtime notification regardless of the time of day.

Uptime Robot (free) + App Engine (free) + Twilio (cheap) = almost free downtime alerts!
