All Facebook users were in Facebook jail for six hours Monday while the social media site experienced an outage.
Instagram and WhatsApp were also down for six hours from just before noon and into the evening.
On Tuesday, Facebook reported that communication on all three sites was interrupted because of configuration changes on the routers that coordinate network traffic of its 3.5 billion users. Facebook insisted that no data breach occurred during the outage. Later on Tuesday, Facebook engineers explained that the social media site’s backbone connection shut down during what was supposed to be routine maintenance.
The configuration changes were scheduled just days after a hearing on Sept. 30 by the Senate Subcommittee on Consumer Protection, Product Safety and Data Security about Facebook-owned Instagram’s potentially negative impact on children, especially young girls. On Oct. 3, CBS’s “60 Minutes” aired a segment in which Facebook whistleblower and data scientist Frances Haugen alleged that Facebook is aware its platform spreads misinformation and hate. Haugen testified before the subcommittee on Tuesday.
Twitter responded to the social media site’s outage on Monday by tweeting: “hello literally everyone.”
As Facebook regained its presence on the Internet Monday evening, it posted on Twitter: “To the huge community of people and businesses around the world who depend on us: we’re sorry. We’ve been working hard to restore access to our apps and services and are happy to report they are coming back online now. Thank you for bearing with us.”
