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.
Given than many people had no problems with the stream, it is unlikely to have been an origin problem but more likely the mechanism to fanout quickly to OCAs. Normally latency to an OCA doesn’t matter when you’re replicating new catalogs in advance, but live streaming makes a bunch of code that previously “didn’t need to be fast” get promoted to the hot path.
I was watching a pirated, live retransmission of the event on Twitch (in Portuguese), and there was zero buffering on my end.
