Use this as a supplement to other monitor tools. Found the function for checking the accessibility of websites from 15 regions of the world particularly interesting - this often led to false alarms at first, as far distant regions registered excessively long waiting times and the website was then reported as unavailable overall. But on the one hand, this can be corrected, and on the other, it has motivated to work on the performance of various sites. All in all, a robust tool to complement your own monitoring landscape.
