Famous outages along with deep postmortems?

I just finished reading the Roblox outage postmortem (trending on HN: https://blog.roblox.com/2022/01/roblox-return-to-service-10-28-10-31-2021/). I learned a lot reading about it and found myself thinking "surely there's other well-written postmortems that are a doozy". Does anyone know a good resource where I can find a compilation of such outages? If they're classified/tagged then even better :)

If you'd like to go beyond technical postmortems, I've found the IAEA reports on radiological accidents etc to make very interesting technical reading. Abstractly there is a often something to be learned about having a good playbook to deal with specific events.

I did start a site where I was logging what I could at outagereports.net, but I let it lapse when cpanel fees shot up. Dan Luu's site referenced below is a good source [1]. I think also there is a big list on github somewhere of all k8s-caused outages.

Project Zero's exploit reporting is fantastically in-depth: https://googleprojectzero.blogspot.com
