This is exactly how I understood your point @melip. About half of the nodes didn't upgrade on time and you were just suggesting another option for people out there, aside from "do it yourself". Yes, of course, if you have the knowledge, the time and the commitment you can manage all your day-to-day tasks yourself, otherwise you can pay someone else to do it for you. It is a personal opinion whether the price of a service is too high or too low and it is based on how an individual values their own time.
