That’s not entirely fair. ST has demonstrated great redundancy. If they can’t bring down your system with their selection of terrible technologies such as NoSQL databases (essentially a key-value pair, what in the 1970s we called a “file system”), they can bring it down with a buggy mobile app update. If that doesn’t work, they can lose all the triggers for your events. And, if your system survives that, they hit it with their own approach to a Denial-of-Service, done in this case by downing the service.
If that’s not redundancy, I don’t know what is!
