Funny enough: when I started working with cloud, it was first time when I met absolutely unpredictable reliability in real life. Some instances worked for months without any issues, while some died within minutes after start. Of course, many things changed since then (it was about 10 years ago). Fortunately, such a behavior helped us build system able to survive in such a harsh environment :)

I also have unpleasant memories of instances going into Erred state.
