Famous outages along with deep postmortems?
2 by fizwhiz | 0 comments on Hacker News.
I just finished reading the Roblox outage postmortem (trending on HN: https://ift.tt/3nJ6zsw). 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 :)
