NEW YORK (AP) — Netflix, Instagram and Pinterest are using Twitter and Facebook to update subscribers after a Virginia storm caused server outages for hours.

Netflix and Pinterest restored service by Saturday afternoon. Instagram engineers are working to restore service but no data was lost. The three websites are customers of Amazon Inc.’s web services division.

The storm killed six 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 says employees are working on remaining issues that may affect performance.
