In this age of digitalization as even the smallest companies start their internet services, nobody seems to take notice about the fact that even the greatest product or service of them all does not bring you customers if your frontend doesn´t work. As I have been interested in service monitoring for a long time, I made a test environment for myself where I monitor my site, cloud services, surveillance systems etc. If my site goes down or gets hacked and the content changes, my mobile alerts me immediately and I can react. Best of all, most of these systems are free, you just have to know where to look and how to use them.
