I don't think you can say that. They might know what happened, but it could still be hard to recover from. Catastrophes happen. If you deploy something that has a destructive migration you can't easily roll back without reverting to a backup and there's a problem that you've not seen in QA then you're in for a bad time. This is compounded if you also discover your backup process hasn't worked properly for a while. If that happens you're facing some serious downtime, and the dilemma of either trying to fix the problem, or trying to rollback to the last working backup. There's a good reason why grumpy old devs like me insist on writing docs, having playbooks, testing everything including non-code stuff, and we still fear major deploys. I have scars from exactly those sorts of disasters. Hopefully the devs at Circle get past this with as little stress as possible, and they learn from what went wrong. |
