SAN FRANCISCO (CBS / AP) — Netflix, Instagram and Pinterest were using Twitter and Facebook to update subscribers after a Virginia storm caused server outages for hours.

Los Gatos-based Netflix and Palo Alto-based Pinterest restored service by Saturday afternoon. San Francisco’s Instagram engineers were working to restore service but no data was lost. The three websites are customers of Amazon Inc.’s web services division.

The storm killed 13 people and knocked out electricity for hundreds of thousands in the Mid-Atlantic region.

Amazon spokeswoman Kay Kinton told The Associated Press in an email that the storm cut power to some of company’s operations. Service has been restored for most customers, Kinton said.

Netflix, a video streaming service, tweeted that subscribers should reconnect if they still experienced problems.

The online scrapbook service Pinterest said employees were working on remaining issues that may affect performance.
