I wonder what Reddit devops is like, I find it so strange that such a trafficked website can’t handle rollouts without what appears (on the outside) to be a full reboot. And also strange that the rollout takes so long. Makes me think they are doing something naive like running on naked vms and having one guy running a script to take them down, update os, redeploy new binary, etc. all at once. Then probably encountering issues and live debugging them until it works again
