Each downtime is an opportunity to learn the weaknesses of your own system.
There are certain scenarios you have no control over (upstream problems), but others have contingencies. I enjoy working out these contingencies and determining whether the costs are worth the likelihoods - and even if they're not, that doesn't necessarily mean I won't cater for it.
When my rental was damaged by a neighbouring house fire, we were kicked out of the house the next day. This was a contingency I hadn't planned well for.
I have long thought that I need my homelab/tools to have hardcases and a low power, modularity to them. Now I am certain of it. Not that I need first world technology hosting in emergency situations, but I am now staying with family for at least a few weeks, maybe months, and it would be amazing to just plonk a few hardcases down and be back in business.
