> If the server hall loses both primary and backup power, there is a real risk that the administrator does need to travel there to bring the machines back up. That would be one of the major trade offs, through I would still recommend administrators to do that, compared to the risk of an unencrypted disk getting lost, stolen, or cases where someone comes in and takes all the servers. Yeah, I agree with all of this. My nitpick is just basically requesting the doc talk about this being a conscious tradeoff where your infra availability and your lack of tolerance for frequent fail-closed events might lead you to intentionally weaken the security guarantees by lengthening the timeouts. In other words, you set the timeouts as short as you can tolerate, based on your infra.
