Alert Speed is a calculation performed by StatusCake to give you a rough idea of the maximum amount of time your test may take to alert you on downtime.

It uses the metric

Check Rate + Alert Delay Rate + (Confirmation Servers * Timeout)

Reducing these settings will reduce your Alert Speed and thus you will get alerted quicker – however do not reduce your Confirmation Servers too low to avoid risk of false positives.

The value presented in the dashboard is the slowest possible case (worst case event) and in most cases the actual Alert Speed will be much higher
