Many viewers had their screens freeze or endlessly buffer, with some crashes reported as well. The 60 million who tuned in were an all-time high for the service. In a note to employees, Netflix Chief Technology Officer Elizabeth Stone admitted that there were problems.

Netflix subscribers across the country took to social media Friday evening complaining that the steaming service was buffering during the opening fight that was part of the highly touted Jake Paul-Mike Tyson card.

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.
