Facebook has blamed a “server configuration change” for the outage that affected its social media platforms for more than 14 hours yesterday.
“We've now resolved the issues and our systems are recovering. We’re very sorry for the inconvenience and appreciate everyone’s patience,” the company said in a statement.
The explanation rebuffs speculation that the problems were caused by a cyber attack or a so-called route leak, an error in internet routing that can lead to large outages.
Yesterday, as a result of a server configuration change, many people had trouble accessing our apps and services. We've now resolved the issues and our systems are recovering. We’re very sorry for the inconvenience and appreciate everyone’s patience.

Facebook had already denied it had fallen victim to a distributed denial-of-service (DDoS) attack.
The outage, believed to be the longest in the social media site’s history, impacted users of Facebook, Whatsapp and Instagram for more than 14 hours.
The outage led to an uproar from Facebook users, who took to Twitter to complain about the problems.
The problems also sparked concern among advertisers, who could not access Facebook's Ad Manager platform and may have been paying for campaigns that users were unable to view.
Facebook, which has roughly 2.3bn monthly users, recovered from the interruption yesterday morning and its services are currently operating normally.
