Last night was the big night forTV livestreaming services—until it wasn't. Hulu's live stream of Super Bowl LII cut out completely for some users, just as the Patriots attempted to rally to close the gap in the final moments of the game. And some PlayStation Vue users experienced intermittent disruptions during the first part of the game.

But to be fair, streaming services weren't alone in their troubles: NBC's broadcast also cut out. Viewers saw a blank screen with no audio for a few seconds, but NBC was quick to explain on Twitter that no "game action or commercial time were missed."

The problems with Hulu and Vue were more significant. Vue users complained on Twitter that they were seeing intermittent disruptions to the stream at the beginning of the game, though it seemed limited to only certain users or markets. Sony tweeted that the issue had been resolved at 7:48pm (EST):

PS Vue users: We apologize for the brief interruption some users experienced during the Super Bowl earlier today. It has since been resolved to full service.

The Hulu interruption happened late in the game, at 10:00pm (EST). Some users—again, it may have been market-dependent—said the video and audio dropped out for them. They also reported two different error messages: one that said the content could not play because of "rights restrictions," and another that simply read, "There is currently no content to play."

Naturally, Hulu also took to Twitter. The company suggested that users restart their Hulu apps to fix the problem:

We are aware of a technical issue that is impacting some of our NBC feeds. At this time we recommend users to close and relaunch their Hulu App as a workaround.

Sunday wasn't the first time either service has experienced disruptions, but in the United States, the Super Bowl is often one of the biggest TV nights of the year in terms of viewership. While neither company has explained in detail how the problems occurred, the "rights restrictions" error message on Hulu might give a clue. While these are newer services from modern tech companies, much of the infrastructure for television is built on much older technologies. Hulu's failure may have had as much to do with that foundation as it had to do with Hulu's own tech. But until more details are shared, there's no way to be certain.

The appeal of these platforms is closely tied to live events, though, so it's important for both Hulu and PlayStation Vue to earn subscriber trust by handling these major broadcasts without a hitch. The 2018 Winter Olympics will also begin airing on NBC later this week, and you can expect a lot of users to sign up to Hulu, YouTube TV, and PlayStation Vue just to watch. Here's hoping for a blackout-free winter games.
