Kathmandu, October 9. On Friday night, Facebook suffered its second outage of the week. Instagram suddenly crashed for two hours.

Minutes later, facebook wrote on Twitter, “We know some of you may be having some issues using Instagram right now. We’re so sorry and are working as quickly as possible to fix.”

The engineering teams restored services two hours later and confirmed that the problem was caused by a “faulty configuration” in the firm’s current data server system.

For over six hours on Monday, Facebook and its sibling apps, Instagram and Whatsapp, vanished from the internet. Downdetector claimed that its online survey technology had never seen 14 million complaints about a single website in a single day. Downdetector dubbed Monday’s outage as “facebook’s biggest failure in history.”

Millions of users were diverted to other social media sites as a result of Monday’s outage. “Telegram” reported that 70 million additional subscribers joined up for their services during the six-hour downtime. Facebook has been losing customers since January when it announced that its new user data policy permitted tracking down of users’ personal information.

The outage had a significant influence on the trading of Facebook’s stocks. On Monday night, the company’s stock dropped by 4.9 percent. The valuations have already tumbled by roughly 13% within the last month.
