Facebook Chief Executive Mark Zuckerberg apologised on Tuesday (October 5) following a six-hour social media outage that affected Facebook, Instagram and Whatsapp.
In a post on Facebook, Zuckerberg said the social media platforms were coming back to normal. “Sorry for the disruption today — I know how much you rely on our services to stay connected with the people you care about,” he wrote.
Facebook and its WhatsApp and Instagram apps went dark at around noon Eastern time (1600 GMT), in what website monitoring group Downdetector said was the largest such failure it had ever seen.
Around 5:45 pm ET (0045 GMT), some users began to regain partial access to the three apps.
The outage was the second blow to the social media giant in as many days after a whistleblower on Sunday (October 3) accused the company of repeatedly prioritizing profit over clamping down on hate speech and misinformation.
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. A similar outage at cloud company Akamai Technologies Inc took down multiple websites in July.
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.
