Superhero Luke Cage can thank Netflix's engineers for coming to his rescue.

The streaming service was down for more than two hours Saturday, one day after the debut of a live-action series with the Marvel Comics hero.

In a Twitter message posted at about 3:30 p.m. EDT Saturday, Netflix acknowledged it was aware of streaming issues and was working quickly to solve them.

Netflix users had begun complaining on Twitter that the site was down about a half-hour earlier.

Shortly before 6 p.m. EDT, Netflix tweeted that not all superheroes wear capes, adding, "Engineers to the . We're back."

Netflix did not immediately respond to an email request for details on the problem, including how widespread it was or its cause.
