I have my own horror story, and that's not even about the cloud, just how centralizing a service magnifies issues. I work for near FAANG company who still sends important email information out to people. One day, many years ago, a new gmail feature landed: automatic smart tabs - and ALL of our email started landing in promotions. And those mails were send from IP addresses which were dedicated for these and only these kind of email, so we started to panic. We started going through the correct channels for reporting this as a problem, at which point we got a "cheers, we'll get back to you in 2 weeks". At that point we were certain we were loosing money in the millions soon, so we walked over to marketing - Google PPC (pay per click) to be specific, and asked them to get hold of someone high enough at Google, we don't care how, or over what channel. Within an hour, the change in gmail to put everything in promotions that was "noreply@" was rolled back, and our arses were saved. If we were still in the early 2000s with countless small email servers and providers, if one of them done this, their customers would be angry at them. But since people believe Gmail is their saviour - and because nobody can get hold of anyone at google to report a problem - now it was our fault, despite the fact that we had absolutely no idea what went wrong, and there were no changes on our side. My summary? Fuck the cloud and the centralized services; I want the small, loosely connected internet services back.
