Facebook and Instagram were back in business on Monday afternoon after a six hour shutdown that cost CEO Mark Zuckerberg an estimated $7 billion.
WhatsApp, owned by Facebook, appeared to still be offline, as the company’s technicians battled to restore service after a global outage.
Technicians had attempted a ‘manual reset’ of its servers on Monday afternoon, which appeared to have worked.
A small team of employees was sent to Facebook’s data center, in Santa Clara, California, to try a ‘manual reset’ of the company’s servers, according to an internal memo obtained by The New York Times.
Facebook’s Chief Technology Officer offered his ‘sincere apologies’ as a global outage of the website, costing the company $50billion and CEO Mark Zuckerberg $7billion and counting.
The cause of the outage is believed to have been changes made to Facebook’s systems at 11.50am EST.
It is believed they were caused in error and were not a cyber attack, but Facebook is yet to confirm the cause of the outage.
It sparked global outages that are detrimental to online businesses and decimate the company’s ad-wielding power.
At 3.50pm, four hours after the outage began, CTO Mike Schroepfer tweeted: ‘*Sincere* apologies to everyone impacted by outages of Facebook powered services right now. We are experiencing networking issues and teams are working as fast as possible to debug and restore as fast as possible.’
The cause of the outage is believed to be changes made to Facebook’s Border Gateway Protocol.
The BGP allows for the exchange of routing information on the internet and takes people to the websites they want to access by helping them identify them on what is known as a domain naming system – a directory of websites.
Facebook’s changes included withdrawals which removed its properties from the domain naming system it operates and essentially made it impossible for anyone to connect to the sites because they could no longer be found online.
As the company scrambled to fix the issue, share prices fell by more than 5 percent, reducing the company’s total value from $967billion on Friday afternoon to $916billion by Monday’s closing bell. Zuckerberg’s stake shrank by $7billion.
