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 :)
