Roblox Return to Service 10/28-10/31 2021 (via) A particularly good example of a public postmortem on an outage. Roblox was down for 72 hours last year, as a result of an extremely complex set of circumstances which took a lot of effort to uncover. It’s interesting to think through what kind of monitoring you would need to have in place to help identify the root cause of this kind of issue.

Using the undocumented Fly GraphQL API
— [Fly](https://fly.io/) has a GraphQL API which is used by some of their own tools - I found it while [browsing around their code](https://github.com/superfly/flyctl/blob/603b0adccf5416188eabaa7dc73f9c0ec88fa6ca/api/resource_volumes.go#L5-L40) on GitHub.
