The TV and film site stopped working at around 6:45pm on Wednesday.
A Netflix spokesman tweeted shortly after 7pm to say that the service was “back up” and apologised for the “hiccup”.
But complaints from users continued to pour in.
One customer, @lexUsplease, tweeted: “Netflix is down, isn’t it? First it was no connection than I got logged off.”
Another, @ashlinnweldonn, said: “Netflix is down. I’m triggered. Just want to watch Jane the Virgin.”
And @HiThereImEffio tweeted: “It really sucks that @netflix has been down.
“I’m bored and trying to watch Sense 8.”
