The social media giant, which is the second largest digital advertising platform in the world, was losing about US$545,000 in US ad revenue per hour during the outage, according to estimates from ad measurement firm Standard Media Index. Several Facebook employees who declined to be named said that they believed that the outage was caused by an internal routing mistake to an Internet domain that was compounded by the failures of internal communication tools and other resources that depend on that same domain in order to work. "We’re starting to slowly and carefully get WhatsApp working again. "Apologies to everyone who hasn’t been able to use WhatsApp today," tweeted the messaging app. "We’ve been working hard to restore access to our apps and services and are happy to report they are coming back online now. "To the huge community of people and businesses around the world who depend on us: we're sorry," the team tweeted on Monday.

A similar outage at cloud company Akamai Technologies Inc took down multiple websites in July.įacebook's engineering team apologised as the apps started to come back online. The error message on Facebook's webpage suggested an error in the Domain Name System (DNS), which allows web addresses to take users to their destinations. Soon after the outage started, Facebook acknowledged users were having trouble accessing its apps but did not provide any specifics about the nature of the problem or say how many users were affected by the outage. "To every small and large business, family, and individual who depends on us, I'm sorry," Facebook Chief Technology Officer Mike Schroepfer tweeted, adding that it "may take some time to get to 100 per cent". The outage was the second blow to the social media giant in as many days after a whistleblower on Sunday accused the company of repeatedly prioritising profit over clamping down on hate speech and misinformation. In a blog post late on Monday, Facebook said the outage was caused by a "faulty configuration change", without specifying who executed the change and whether it was planned.
