This is the whole point of chaos engineering that was invented at Netflix, which tests the resiliency of these systems.
I guess we now know the limits of what "at scale" is for Netflix's live-streaming solution. They shouldn't be failing at scale on a huge stage like this.
I look forward to reading the post mortem about this.
Everyone keeps mentioning at scale. I seriously doubt this was an "at scale" problem. I have strong suspicion this was a failure at the origination point being able to push a stable signal. That is not an "at scale" issue, but a hubris of we can do better/cheaper than broadcasting standard practices
