Facebook Inc. laid the blame on a global service outage that kept its social media platforms offline on Monday on a network configuration issue, according to Bloomberg on Tuesday.

  • On Monday night, the company’s engineering team wrote in a blog post that the disruption to network traffic had a cascading effect on the way data centers communicate, leading to the stoppage of services.
  • The technical problem took Facebook’s key social network, its photo app Instagram and its WhatsApp and Messenger services offline for hours, marking one of the longest and significant failures in recent memory.
  • After an initial slight decline of 4.9% on Monday, the stock was up 1.5% to $331.20 at 4:30 a.m. in New York in pre-market trading.
  • Facebook’s outage had a massive impact, immobilizing a wide range of services that more than 2.75 billion people use daily to communicate, conduct business, and consumer news.

Facebook’s internal tools and communication systems were affected by the disruption, adding to the problem for engineers working to determine and solve the issue. FB up 1.22% Pre-market trading
