Depends on your setup. For a simple git server on AWS I might have it on a single-node ASG so that when something terminates the instance, the ASG notices and launches a new one. The initialization scripts would then attach and mount a pre-existing EBS volume and start services. Very simple to set up, and as long as your data volume is not lost (which can happen, but is very rare), such a system would recover from a host failure by itself faster than most people could react to it going down. In the unlikely case that you lose the EBS volume, you'd just recover from snapshots manually.
