“We are working hard to restore access to our apps and services and are happy to report that they are now back online. Thank you for staying with us.”

The social media giant, the world’s second largest digital advertising platform, was losing about $545,000 in US ad revenue per hour during the outage, according to estimates by advertising measurement firm Standard Media Index.
