The Web site of popular online movie rental company Netflix suffered an outage early Monday morning, and the company is working to fix the problem swiftly, the company said.

The Web site went down at 7 a.m. Pacific Time, said Steve Swasey, a company spokesman. The company declined to comment on reasons for the outage.

It was an unplanned outage and the company's engineers are feverishly working to fix the problem, Swasey said.

"It's very rare," Swasey said. An outage like this hasn't happened to Netflix in a long time, Swasey said.

The outage is even more frustrating as Netflix prides itself on providing customer service to users, Swasey said. About 90 percent of Netflix's customers were satisfied with the company's customer service, according to a Nielsen survey in December 2007.

Netflix offers DVDs and streaming movies to about 8 million customers. The company recently added a movie streaming service for game consoles.
