Yes and no. It's not the "same" but this is a solved problem. Fastly regularly delivers the Super Bowl to 10x as many viewers.

Netflix dropped the ball hard

Fastly says they do 6M ccv for superbowl (i'm actually surprised they let them do the entire thing and don't mix different CDNs) and I'm not sure they do encoding and manifest serving - they might just cache/deliver chunks. Do you really think tyson vs other guy was only 600k ccv? I'd be shocked if Netflix can't handle this.
