All the social network said Thursday was that the outages, which affected users and advertisers worldwide, resulted from a “server configuration change.” It offered no further details. Facebook and its apps — Instagram, Facebook Messenger and WhatsApp — started experiencing problems midday Wednesday on the U.S. East Coast. Facebook did not say how many users were affected or why the outage took so long to fix. It didn’t help that it took Facebook so long to explain what was going on, he said. While some less active users may not have noticed that Facebook services were down, other frequent users and advertisers keenly felt its absence.
