I've had the odd problem with hanging/stalling instances before I learned to design for the cloud. Now those instances automatically get replaced with new ones and nobody would even notice if I didn't pipe the notice through to Slack. Of course, this only works if whatever you use it for allows for this. However, in most cases not using EC2 as a stateless throwaway computing resources is simply a matter of bad infrastructure design.
