Facebook and its Instagram and WhatsApp platforms are back online after a massive global outage plunged the services and the businesses and people who rely on them into chaos for hours.
Facebook said late Monday that “the root cause of this outage was a faulty configuration change” and that there is “no evidence that user data was compromised as a result” of the outage.
The company apologized and said it is working to understand more about the cause, which began around 11:40 a.m. Eastern Monday.
Facebook was already in the throes of a separate major crisis after whistleblower Frances Haugen, a former Facebook product manager, provided The Wall Street Journal with internal documents that exposed the company’s awareness of harms caused by its products and decisions. Haugen went public on CBS’s “60 Minutes” program Sunday and is scheduled to testify before a Senate subcommittee Tuesday.
Haugen had also anonymously filed complaints with federal law enforcement alleging Facebook’s own research shows how it magnifies hate and misinformation and leads to increased polarization. It also showed that the company was aware that Instagram can harm teenage girls’ mental health.
The Journal’s stories, called “The Facebook Files,” painted a picture of a company focused on growth and its own interests over the public good. Facebook has tried to play down their impact. Nick Clegg, the company’s vice president of policy and public affairs, wrote to Facebook employees in a memo Friday that “social media has had a big impact on society in recent years, and Facebook is often a place where much of this debate plays out.”
The outage didn’t exactly bolster Facebook’s argument that its size and clout provide important benefits for the world. London-based internet monitoring firm Netblocks noted that the company’s plans to integrate the technology behind its platforms — announced in 2019 — had raised concerns about the risks of such a move. While such centralization “gives the company a unified view of users’ internet usage habits,” Netblocks said, it also makes the services vulnerable to single points of failure.
“This is epic,” said Doug Madory, director of internet analysis for Kentik Inc, a network monitoring and intelligence company. The last major internet outage, which knocked many of the world’s top websites offline in June, lasted less than an hour. The stricken content-delivery company in that case, Fastly, blamed a software bug triggered by a customer who changed a setting.
For hours, Facebook’s only public comment was a tweet in which it acknowledged that “some people are having trouble accessing (the) Facebook app” and said it was working on restoring access. Regarding the internal failures, Instagram head Adam Mosseri tweeted that it feels like a “snow day.”
Mike Schroepfer, Facebook’s outgoing chief technology officer, later tweeted “sincere apologies.”
In Monday night’s statement, Facebook blamed changes on routers that coordinate network traffic between data centers. The company said the changes interrupted the communication, which had “a cascading effect on the way our data centers communicate, bringing our services to a halt.”
There was no evidence as of Monday afternoon that malicious activity was involved. Matthew Prince, CEO of the internet infrastructure provider Cloudflare, tweeted that “nothing we’re seeing related to the Facebook services outage suggests it was an attack.”
Facebook did not respond to messages for comment.
about the attack or the possibility of malicious activity.
While much of Facebook’s workforce is still working remotely, there were reports that employees at work on the company’s Menlo Park, California, campus had trouble entering buildings because the outage had rendered their security badges useless.
