Makes sense to me. I remember several lunch conversations at FB about whether or not we even could restart the site with totally cold caches. I’m sure it was possible but it wouldn’t have been clean or pretty.

We did restart reddit with cold caches a few times when I was there. It took hours to recover but eventually caught up if it happened near peak. If we did it during low traffic it wasn't too bad.

But that was 13 years ago, no idea how it would do today. :)

I’m sure Facebook could too (their disaster recovery planning and drills were always top notch) but I’m glad I won’t be oncall if it ever happens :-D

so you're saying, we just have to knock it out once, and it'll be gone forever? that makes things easier ...
