The massive Facebook outage that began this morning has cost Facebook, Inc. $7 billion in revenue and stock losses so far today.

Facebook and its subsidiaries WhatsApp and Instagram all went down around 11 a.m. on Monday, Oct. 4.

According to reports, Facebook staffers are locked out of their offices because their badges don't work.

NY Times' Sheera Frenkel tweeted:

"Was just on phone with someone who works for FB who described employees unable to enter buildings this morning to begin to evaluate extent of outage because their badges weren't working to access doors."

The massive outage comes a day before a whistleblower is set to testify before Congress on Tuesday, Oct. 5.

Former Facebook product manager Frances Haugen told 60 Minutes on Sunday, that Facebook helped promote the January 6 riots and encouraged hate speech on the platform for profit.

"[Facebook is] paying for its profits with our safety," she said.

According to the Verge, Haugen's LinkedIn profile shows she left the company earlier this year.

She said she didn't "trust that they're willing to invest what actually needs to be invested to keep Facebook from being dangerous."

Haugen claims algorithm changes rolled out in 2018 are meant to drive engagement and the company decided the best engagement are posts that promote fear and hate in users.

"Its easier to inspire people to anger than it is to other emotions," Hagen said.

Major websites such as the BBC, New York Times, Bloomberg News, The Guardian, Reddit, and the Disqus commenting platform were hit by a massive Internet outage ovrnight.

The Internet outage affected Amazon.com and Fastly.com, which provide updated news content to many websites.

The BBC and United Kingdom's government page, were temporarily down during a massive outage early Tuesday, NBC News reported.

Social media users took to Twitter.com early Tuesday to say most of the websites they normally visit were down.

Fastly.com, an American cloud services provider, issued an update on its status page at about 5:58 a.m. ET., saying the "issue has been identified and a fix is being implemented."

It isn't clear if the websites were hit by a Russian cyberattack.

The global outage comes a day after the U.S. Department of Justice announced it had recovered most of the cryptocurrency ransom paid to a criminal hacker group that hit Atlanta-based Colonial pipeline, causing gas prices to surge nationwide in mid-May.

The DOJ used "sophisticated technology" to recover $2.3 million of the $4.4 million in Bitcoins paid to the Russian-based Darkside hacker group that compromised Colonial's IT system.

Colonial paid the ransom to the hacker group within 48 hours after the cyberhack in May.

JBS meat processing company was also hit by ransomware, resulting in the shutdown of all of its North American meat packing plants earlier this month.

"The sophisticated use of technology to hold businesses and even whole cities hostage for profit is decidedly a 21st century challenge," said U.S. attorney general Lisa Monaco, during a press conference on Monday afternoon. "Today we turned the tables on DarkSide."
