Facebook blamed the nearly six-hour crash on Monday for a “false configuration change” that prevented the company’s 3.5 billion users from accessing its social media and news services such as WhatsApp, Instagram and Messenger.
The company did not specify who implemented the configuration change and whether it was planned in a blog post late Monday.
Many Facebook employees who declined to be named had previously told Reuters that they believed the crash was due to an internal error in how Internet traffic was directed to its systems.
Staff said failures of internal communication tools and other resources that depend on the same network to work add to the error. Security experts say both a careless mistake or the sabotage of a local can be credible.
“At this point we would like to clarify that we believe that the root cause of this crash is a faulty configuration change,” the Facebook blog said.
The Facebook crash is the largest ever monitored by Downtector, a web surveillance team.
The crash comes as a second blow to the social media company, several days after a whistleblower on Sunday accused the company of prioritizing profits over control over hate speech and misinformation.
Shares of Facebook fell 4.9 percent, the biggest daily fall since last November, amid widespread selling of tech stocks on Monday as the world rallied for competing applications such as Twitter and TicTac. Shares traded up half a percent in hourly trading following the resumption of service.
“Sorry to every small and big business, family and individual who relies on us,” Facebook CEO Mike Schropper tweeted, adding, “It may take a while to reach 100 percent.”
“Facebook basically locked its car in its car,” tweeted Jonathan Zidrain, director of Harvard’s Bergman Klein Center for Internet & Society.
Twitter announced on Monday that it was using more than normal, which led to some issues with accessing posts and live messages.
In one of the most popular tweets of the day, video streaming company Netflix shared a meme titled “Instagram & Facebook Crashing” on its new hit show Suide Game, which shows a person named “Twitter” on the verge of collapse named “Everyone”.
Within the Facebook group for ad buyers, a lot of people today searched for “how to run Google ads for customers” after a member turned service.
Facebook, the world’s second-largest online ad seller after Google, loses about $ 545,000 (about Rs 4 crore) per hour in US advertising revenue, according to estimates by advertising media outlet Standard Media Index.
However, past unemployment in Internet companies has had a somewhat long-term impact on their revenue growth.
Services of Facebook, consumer applications such as Instagram, workplace tools that it sells for businesses and internal projects, Eastern time (9:30 pm IST). Access resumed at 5:45 pm (3:15 am IST).
As soon as the crash started, Facebook acknowledged that users had trouble accessing its processors, but did not provide any details about the nature of the problem or how many users were affected.
The error message on Facebook’s web page suggested an error in the Domain Name System (DNS), which allows web addresses to take users to their destinations. A similar crash at cloud company Agama Technology took over several websites in July.
On Sunday, Francis Hogan, who worked as a product manager at the Civic Information Group on Facebook, revealed last week the U.S. Senate inquiry into Instagram’s harm to whistleblowers and teenagers who provided documents based on a recent Wall Street Journal investigation.
Houghton on Tuesday urged the same Senate subcommittee to regulate the company, which plans to compare it to tobacco companies that have denied for decades that smoking does not harm health, according to evidence prepared by Reuters.
