A big audience tuned in, but consumers faced outages and buffering throughout the live event from AT&T Stadium.

Many of the complaints about a Netflix outage on social media were centered on the eight-round heavyweight boxing match between Mr. Tyson, a former heavyweight world champion, and Mr. Paul, a YouTuber. The livestream for that fight began at 10 p.m. Eastern time, before the fight started.

The fight attracted a huge amount of media coverage. Tyson is one of the most famous men on the planet, while Paul drew in a younger audience. According to Paul, 120 million viewers watched it live globally on Netflix. The tech firm has said it will reveal further viewing figures on Tuesday.
