Netflix services such as online streaming and the ability to order DVDs went down Sunday night for a few hours, sending disgruntled customers to complain on Twitter.
As of 3:30 a.m. Eastern time Monday, the company said that it had its Web site and instant-watch services back online but was still having some issues activating devices.
Following a series of high-profile attacks on Internet services, some users expressed concern that Netflix had also been the victim of a cyber attack, some assuming that the hacker group LulzSec was responsible.
But Netflix spokesman Steve Swasey said the outage was not due to a malicious cyber attack.
“It was a technical issue that we fixed,” Swasey said.
The company has experienced outages in the past releated to technical issues, and normally has issued a credit to affected user accounts.
Some Sony movies released through StarzPlay are unavailable for streaming following a small contract dispute between Sony and Starz, the company said in a blog post Friday.
