LOS ANGELES - 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 rescue. 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.
